This document presents many of the rules in GURPS Fourth Edition that refer to measurements, and converts them to the world-standard SI (modern metric system) measurements.
The emphasis is on enabling smooth game play using these units, with precision a desirable but secondary quality. This is consistent with the original GURPS material, which clearly takes liberties with precision when necessary to allow manageable measurement quantities to be used in play.

The main changes that will affect users of this document are:
All mentions of "yard" now use "metre". This is a very convenient near-equivalence, because GURPS uses this measure for a great many things, especially in combat. Simply replacing the unit for game purposes allows most of these quantities (those below a few hundred yards) to remain unchanged.
Usage of feet is less amenable to this; substitutions have been fudged in favour of easier decimal calculations rather than requiring users to deal with third-of-a-metre quantities.
Weights that were in pounds are now in kilograms. This results in perhaps the most fundamental change to GURPS: a character's Basic Lift secondary characteristic now has a different quantity (half that of the original), and all rules that use BL are also changed accordingly.
The game metric of "1 lb = 0.5 kg" results in some slightly different effects – primarily that an object's weight, and a character's capacity to lift, will both be slightly greater – but the convenience of that simple conversion is judged to be worth it.
One cosmetic effect of this change is to make BL look even more like it belongs in the system: the standard human ST of 10 results in BL 10.
The "cubic foot", used for dry volume in original GURPS, has no corresponding commonly-used SI unit at the same degree of magnitude. This document uses cubic centimetres or (for larger volumes) cubic metres, which result in numbers considerably larger or smaller, respectively, than the same quantities in the original material.
The temperature range comfortable for humans is a 30° band between 2°C and 32°C. Changes of temperature are fudged to half the quantity from the original material. This is simply a game-metric conversion of Fahrenheit scale to Celcius, but since both use the degree symbol (°) for their unit, some care is required to ensure the correct scale is being used.
Many other conversions are less simple to calculate without reference to formulae and second-guessing the meaning behind rules. This document gives pre-figured conversions that take into account the effective results of the quantities and calculations in the original material, allowing users to simply substitute a table or a few sentences of text in most cases.
Many of these ideas or conversions are not of my making; I've followed in the footsteps of greater GURPS gearheads and measurement geeks.

For any conversions not covered by this document, the following conversion chart is an expanded version of the one supplied on p. B9.
U.S. Imperial | Game Metric | Real Metric |

1 inch (in.) | 25 millimetres (mm) | 25.4 mm |
1 foot (ft.) | 30 centimetres (cm) | 30.48 cm |
1 yard (yd.) | 1 metre (m) | 0.914 m |
1 mile (mi.) | 1.5 kilometres (km) | 1.609 km |
1 nautical mile | 2 km | 1.852 km |
1 pound (lb.) | 0.5 kilograms (kg) | 0.454 kg |
1 ton | 1 metric ton | 0.907 metric tons |
1 gallon (gal.) | 4 litres (l) | 3.785 l |
1 quart (qt.) | 1 litre (l) | 0.946 l |
1 ounce (oz.) | 30 grams (g) | 28.349 g |
1 cubic inch (ci) | 16 cubic centimetres (cm³) | 16.387 cm³ |
1 cubic foot (cf) | 30 000 cm³ | 28 317 cm³ |
1 cubic yard (cy) | 0.75 cubic metres (m³) | 0.765 m³ |
Temperature: When dealing with changes in temperature, one Fahrenheit degree is 5/9 the size of a degree Celcius. So a change of 45°F is equal to a change of 25°C. To convert actual thermometer readings, subtract 32 from the Fahrenheit temperature and multiply the result by 5/9. So 95°F is 5/9 of (95-32), or 5/9 of 63, or 35°C. Note that this has the effect that -40°F is equal to -40°C.
The standard scale for temperature is relative to the theoretical “absolute zero”, -273.15°C, represented as 0 kelvin (symbol: K). A change of 1 K is the same size as a change of 1°C.
Radiation: The SI unit of absorbed radiation is the gray (symbol: Gy): one joule of radiation energy absorbed by one kilogram of matter. A radiation absorption of 1 Gy is equivalent to 100 rads.
Pressure: The SI unit of pressure is the pascal (symbol: Pa): one newton of force per square metre. One standard atmosphere (atm) of pressure is equivalent to about 100 kPa.
GURPS Basic Set does not have a particular section for physical constants, but they are mentioned in various places. Some important physical constants used in GURPS:
The thermodynamic point where no more heat can be removed from a system.
A definition (not measurement!) of the speed of light travelling in a vacuum.
The distance light travels in a vacuum in one Julian year.
The mean distance of the Earth's orbit from the Sun.
A distance such that a body, at that distance from an observer on Earth, appears to travel one arc second in the sky as the observer moves across the diameter of the orbit of Earth.
The standard acceleration due to gravity at the Earth's surface.
The mean sea level atmospheric pressure on Earth (at the latitude of Paris, France).

Basic Lift is the maximum weight, in kilograms, you can lift over your head with one hand in one second. It is equal to (ST×ST)/10 kg. If BL is 5 kg or more, round to the nearest whole number; e.g. 16.9 kg becomes 17 kg. The average human has ST 10 and a BL of 10 kg.

Every character has a temperature “comfort zone” within which he suffers no ill effects (such as FP or HP loss) due to heat or cold. For ordinary humans, this zone is 30° wide and falls between 2°C and 32°C. For nonhumans, the zone can be centred anywhere, but this is a 0-point feature for a zone no larger than 30°. A larger zone is an advantage. Each level of Temperature Tolerance adds HT/2 degrees to your comfort zone, distributed in any way you wish between the “cold” and “hot” ends of the zone.

Digging rate depends on the type of soil, the digger's Basic Lift (that is, ST×ST/10), and the quality of the tools available.
Loose Soil, Sand, etc.: A man can dig BL×50 cubic centimetres per minute (cm³/min).
Ordinary Soil: A man can dig BL×25 cm³/min. One man with a pick can break up to BL×100 cm³/min, making it into loose soil, which is easier to remove. The most efficient way to dig is with one man with a pick, and two shovellers clearing behind him.
Hard Soil, Clay, etc.: Must be broken up first by a pick, at BL×50 cm³/min, and then shovelled at BL×50 cm³/min. A lone man with both pick and shovel can only remove BL×15 cm³/min – he loses time switching between tools.
Hard Rock: Must be broken by a pick at BL×25 cm³/min (or slower, for very hard rock!), and then shovelled at BL×25 cm³/min.
All of the above assumes iron or steel tools! Halve speeds for wooden tools (common at TL5 and below). Divide by 4 (or more) for improvised tools – bare hands, mess kits, etc.
To find the time required to dig a given hole, find the volume of the hole in cubic centimetres by multiplying height × width × depth (all in centimetres, or measure in metres and multiply by 1 000 000 for cm³). Then divide the number of cubic centimetres by the digging rate to find the minutes of work required.
Each hour of work costs 1 FP for loose soil, 2 FP for ordinary soil, 3 FP for hard soil, and 4 FP for hard rock.

Your Basic Move determines jumping distance, as follows:
High Jump: (15 × Basic Move) - 25 centimetres. For example, a Basic Move of 6 lets you jump 65 cm straight up. For a running jump, add the number of metres you run to Basic Move in this formula. Maximum running high-jump height is twice standing high-jump height.
Broad Jump: (0.6 × Basic Move) - 1 metres. For example, a Basic Move of 6 lets you jump 2.6 metres from a standing start. For a running jump, add the number of metres you run to Basic Move in this formula. Maximum running broad-jump distance is twice standing broad-jump distance.

Replace all occurrences of "yard" with "metre".
Example: You have ST 12, giving a BL of 14 kg. You need to throw a 55 kg body over a two-metre pit. Divide weight by BL: 55/14 = 3.9. This falls between 3.0 and 4.0 in the Weight Ratio column, so treat it as 4.0. The associated distance modifier is 0.15. Multiplying by ST, your range is 0.15 × 12 = 1.8 metres. Oops! The body just hit the bottom of the pit.

A distant target is harder to hit. As a rule of thumb, a target up to 2 metres away is close enough that there's no penalty to hit. At 3 metres, you have -1 to hit; at up to 5 metres, -2; at up to 7 metres, -3; at up to 10 metres, -4; and so on, with each approximately 50% increase in range giving a further -1 to hit.
Consult the Speed/Range column of the Size and Speed/Range Table to find the exact penalty. For ranges that fall between two values on the table, use the larger penalty. For very distant targets, the table provides distances in kilometres.
Example: Infinity Patrol agent Jenny Atkins is shooting on the firing range. The target is 17 metres away. This rounds up to 20 metres, for -6 to hit.
A fast-moving target is also harder to hit. Consult the same column of the table, but use speed in metres per second (3.6 km/h = 1 m/s) instead of range in metres to find the penalty.
If the target is both distant and fast moving, add range (in metres) to speed (in metres per second), and look up the total in the Speed/Range column to find the penalty to hit. (Do not look up the range and speed penalties separately and add them together! Great range mitigates the effects of speed, and vice versa.)
Examples: Agent Atkins fires her pistol at a Centrum spy who is making a getaway on a speeding motorcycle. Her target is 50 metres away and traveling at 96 km/h, or Move 27. This is a speed/range of 50 + 27 = 77. Per the Size and Speed/Range Table, this gives -10 to hit.

If your weapon or Size Modifier gives you more than one metre of reach, each metre past the first brings the foe 1 m closer to you. This does not bring you any closer to the foe! For example, a greatsword (two-metre reach) would let you fight as if your foe were one metre closer. If you were standing two metres below him, you would fight as though he were only one metre higher. He would not enjoy a similar benefit unless he, too, has long reach.

We measure air pressure in kilopascals (kPa); air pressure at sea level on Earth is 100 kPa.
Trace (up to 1 kPa): Treat an atmosphere this thin as vacuum (see Vacuum).
Very Thin (up to 50 kPa): The air is too thin to breathe. Earth's atmosphere becomes “very thin” above 6 km.
Thin (51-80 kPa): Earth's atmosphere is “thin” between 2 km and 6 km.
Dense (121-150 kPa)
Very Dense (151+ kPa)
Superdense (1 000+ kPa)
These rules assume you are native to 100 kPa and can function normally at 81-120 kPa. If your native pressure differs from 100 kPa, multiply all the pressure ranges above by (your native pressure in kPa/100). For example, if you're native to 50 kPa, a “dense” atmosphere for you would be 61-75 kPa and a “thin” one would be 26-40 kPa.

Make a HT or HT-based Survival (Arctic) roll, whichever is better, every 30 minutes in “normal” freezing weather. For most humans, this means temperatures below 2°C, but see Temperature Tolerance. In light wind (15+ km/h), roll every 15 minutes. In strong wind (50+ km/h), roll every 10 minutes. Additionally, strong wind can dramatically reduce the effective temperature (the “wind chill factor”). Also see the modifiers below:
Situation | Modifier to HT Roll |
---|---|
Light or no clothing | -5 |
Ordinary winter clothing | +0 |
“Arctic” clothing | +5 |

“Velocity” is how fast the character or object is moving in metres per second (3.6 km/h = 1 metre per second).
Reference: | B432. |
---|
Example: A car with 60 HP, moving at 80 km/h (velocity 22) strikes a pedestrian with 10 HP. The pedestrian was fleeing from the car at Move 5, so this is a “rear-end” collision. Collision velocity is 22 (car) - 5 (pedestrian) = 17. The car inflicts (60 × 17)/100 = 10d crushing damage on the pedestrian; the pedestrian inflicts (10 × 17)/100 = 1d crushing damage on the car.

In ordinary hot weather, you will experience no ill effects if you stay in the shade and don't move around much. But if you are active in temperatures in the top 5° of your comfort zone or above – over 27°C, for humans without Temperature Tolerance – make a HT or HT-based Survival (Desert) roll, whichever is better, every 30 minutes.
Modifiers: A penalty equal to your encumbrance level (-1 for Light, -2 for Medium, and so on); -1 per extra 5° heat.
In addition, at temperatures up to 15° over your comfort zone (33-47°C for humans), you lose an extra 1 FP whenever you lose FP to exertion or dehydration. At temperatures up to 30° over your comfort zone (48-62°C for humans), this becomes an extra 2 FP.
Intense Heat: Human skin starts to burn at 72°C; see Flame (p. B433) for damage. Even if no damage penetrates your DR, you will rapidly overheat if the ambient temperature is more than 5 × your comfort zone's width over your comfort zone (e.g., in a fire).

Adventurers are most likely to encounter extreme pressure in super-dense atmospheres (see Atmospheric Pressure) or deep underwater (where pressure increases by about 10 kPa per 1 m of depth). Pressures in excess of your native pressure – 100 kPa, for a human – are not always immediately fatal, but present serious risks.
Divers and mountaineers use precise tables to determine decompression times based on time spent at a given pressure. For game purposes, at up to 200 kPa (about 10 m underwater), a human can operate for any amount of time and return without risk. At up to 250 kPa (15 m depth), a human can safely operate for up to 80 minutes and return without requiring slow decompression. Greater pressures reduce the safe time without slow decompression: at 400 kPa (30 m depth), it's about 22 minutes; at 550+ kPa (45 m depth), there is no safe period.

Move: The first number is Acceleration and the second is Top Speed, in metres/second (multiply by 3.6 to get km/h). These statistics are equivalent to a character's Move and his top speed with Enhanced Move. For ground vehicles, a * indicates a road-bound vehicle, while a ‡ indicates one that must follow rails. For spacecraft, divide Acceleration by 10 to find it in Earth gravities (G), and note that c means the speed of light (300 000 000 m/s).
LWt: Loaded Weight, in metric tons (1 metric ton = 1 000 kg), with maximum payload and a full load of fuel.
Load: The weight, in metric tons, of occupants and cargo the vehicle can carry, including the operator. To find cargo capacity, subtract the weight of occupants (for simplicity, assume 0.1 metric tons per person, including gear).
Range: The travel distance, in kilometres, before the vehicle runs out of fuel.
Draft: For a watercraft, the minimum depth of water, in metres, it can safely operate in.
Stall: For an aircraft, the minimum speed, in metres/second, it must maintain to take off and stay airborne. “0” means it can hover.

When adventurers use a vehicle for transportation, it is usually enough to know how fast it can move (Top Speed, in metres/second) and how far it can travel (Range, in kilometres).

Endurance: Divide Range in kilometres by cruising speed in km/h to determine endurance in hours for situations where “loiter” capability matters more than range. The vehicle must carry provisions in order to take advantage of endurance in excess of one day. Food and water are about 5 kg per person per day, but won't keep for more than a month before TL5 (at TL5+, canned goods and similar rations are available).

Terrain: Figure cruising speed in km/h from Top Speed in m/s as follows:
For a road-bound vehicle (e.g. a normal car), use Top Speed only when traveling on a road. Off road, use the lower of Top Speed and 4 × Acceleration in these formulas.
Example: A luxury car with Move 3/52 gets an average travel speed of 52 × 2.2 = 114 km/h on a paved road (Good). On a dirt road (Average), it could manage 52 × 0.9 = 46 km/h. But off road in Average terrain, it would drop to 3 × 4 × 0.9 = 10 km/h!

A powered vessel moves at Top Speed × 3.5 km/h. A sailing craft moves at Top Speed × 3.5 km/h in ideal wind conditions; actual speed can drop to a fraction of this – or even zero – depending on wind direction and strength. A rowed vessel can only sustain a speed of Top Speed × 2.75 km/h (and even this will eventually fatigue the crew).
Reference: | B466. |
---|
An aircraft's cruising speed is about Top Speed × 2.8 km/h. Powered aircraft can reach Top Speed × 3.5 km/h at the cost of burning 50% more fuel, reducing Range. Supersonic aircraft (Move 325+) can only use their full Top Speed at high altitudes where the air is thin (4.5 km and above). At low altitudes, Top Speed rarely exceeds 315-360 (1100-1300 km/h).

It takes about (0.12 × velocity in m/s)/(Acceleration in G) seconds to reach a given cruising velocity. A spacecraft moving at that velocity takes roughly (0.28 × distance in kilometres)/velocity hours to travel a given distance. For comparison, the moon is around 400 000 km from Earth, and Mars is 55 000 000 km away at its closest approach.
Example: To accelerate to a velocity of 80 000 m/s in a spacecraft with an acceleration of 1.5G would take (0.12 × 80 000)/1.5 = 6 400 seconds, or about 1.8 hours. At a velocity of 80 000 m/s, you would reach Mars in (0.28 × 55 000 000)/80 000 = 192.5 hours.
It is common to give interplanetary distances in “astronomical units” (AU). One AU is 150 million kilometres, the average distance from the Earth to the Sun. Interstellar distances are often given in light-years (9.461 thousand million kilometres) or parsecs (3.26 light-years). Earth's nearest stellar neighbor, Alpha Centauri, is 4.3 light-years away.
To lift into low Earth orbit requires Move 7 800. To achieve planetary escape velocity and leave orbit requires an extra Move 3 300.
Example: A spacecraft in Earth orbit has a delta-v of 200 000. It uses 3 300 to break orbit and 82 000 to accelerate to a cruising velocity (Move 82 000). It drifts at that speed for 1.4 hours to reach the moon, and then use another 81 000 to decelerate to the moon's orbital velocity. Its remaining delta-v is 200 000 - 3 300 - 82 000 - 81 000 = 33 700.
Some superscience space drives don't have to worry about delta-v – the spacecraft can accelerate constantly! The only requirement for such a spacecraft to leave a planet is that its acceleration exceeds the planet's gravity. When it travels long distances, it requires time in hours equal to the square root of (81.75 × distance in millions of kilometres / Acceleration in G) to complete the trip.

Standard communicators are radios. They transmit signals by modulating the intensity, frequency, or phase of long-wavelength electromagnetic radiation. This limits them to the speed of light (300 000 km/s); as a result, they are effectively instantaneous for planetary communications but have a noticeable delay over interplanetary distances. Note also that ordinary radio frequencies cannot penetrate more than a few metres of water.

Money in a new world isn't “legal tender”; it's a commodity. If you bring medieval gold coins to the 21st century, they will sell as curios – or as gold, for perhaps $1 200 per 100 grams.
Reference: | B515. |
---|
Historically, gold and silver were very valuable – and many goods were cheap. For an authentic medieval English (14th-century) economy, treat the $ as a “farthing”: a copper coin about 20 mm across. A silver penny is worth $4 and is 10 mm across; 500 such coins ($2 000) weigh one kilogram. If gold and silver trade at 20 to 1 (a reasonable ratio for much of history), a kilogram of gold is worth $40 000! A man could carry a king's ransom in his backpack.
On the other hand, a GM who wants wealth to be less portable might assume that the $ is a 25-gram silver coin, like a silver dollar. A 25-gram gold piece would then be worth $20. At that rate, 40 coins would weigh one kilogram; a kilogram of gold would be worth only $800. In such a world, precious gems are the only way to carry a large amount of wealth in a small package, and caravans loaded with gold might actually exist!

Note that there is no Speed/Range modifier for a ranged attack at 2 metres or less – shooting a close target is no easier (and no harder) than attacking it in melee combat!
Examples: A man 8 metres away is -4 to hit. A motorcycle rider 40 metres away, traveling at 30 m/s (108 km/h), has a speed/range of 40 + 30 = 70 metres, which gives -9 to hit. A missile passing within 5 metres while moving at 1 km/s has a speed/range of 5 + 1 000 = 1 005 metres, for -17 to hit.

Continue this upward progression indefinitely, with each 10× increase in linear measurement giving +6 to SM or -6 to speed/range modifier.
Example: Erin the archer shoots at a dragon. It is 40 metres away and flying at Move 15 (54 km/h): 40 + 15 = 55 metres. Erin rounds up to 70 metres, for a speed/range modifier of -9. The dragon is 6 metres long, which rounds up to 7 metres, for SM +3. Erin's final modifier to hit is -6.
By using the sum of range and speed, the table ensures that when one of range or speed is large relative to the other, only that factor has a significant impact on the outcome. Small variations in speed are negligible when firing at targets at extreme ranges, and vice versa. If a rocket is moving at 1 km/s, it doesn't really matter whether it's 50 or 100 metres away. If an elephant is 1 km away, it hardly matters whether it is walking at 1 m/s or 2 m/s.
Firing Upward and Downward: For every metre of elevation your target has over you, add one metre to effective range. For every two metres of elevation you have over your target, subtract one metre from effective range; if this would reduce effective range to less than half the real ground distance, use half the ground distance instead.

Drift: You appear at a random location somewhere in a circle with a radius equal to 1% of the distance you teleported (minimum 1 metre); e.g., if you teleported 10 km, you'd materialize somewhere in a 100 m circle around your target.

Replace all occurrences of "yard" with "metre".
For solids and liquids, you can affect up to 5 × (level squared) kg of matter in the form of a single object or amorphous mass. For example, Control 3 (Iron) would let you affect a 45 kg iron ingot or even 45 kg of iron filings in a heap… but against a foe with a 1 kg sword, 2 kg helmet, and 9 kg breastplate, all iron, you could only affect one target, even though the total weight is much less than your limit.
Collective: You still can't affect more than 5 × (level squared) kg of a solid or liquid. For instance, Control 2 (Metal) with Collective lets you affect up to 20 kg of any one metal in a two-metre circle; in the example under Limits of Control, you could affect the sword, helmet, and breatplate.
Natural Phenomena: Area of effect is 0.1 × level kilometres in radius.
For instance, Control 10 (Oceans) could roughen or calm seas in a 1 km radius, for ±3 to die rolls.

Icy Skin: Each level (maximum five) gives him DR 1 – doubled vs. heat/fire – and +1 on rolls to break free, and adds HT/2 degrees to the “hot” end of his temperature comfort zone.
Insulated Skin: Each level gives DR 5 vs. energy, divides radiation dosage by 10, and adds 2.5×HT degrees to the “hot” end of the user's comfort zone.
