This page covers various measurement units and derived units used in Satisfactory.
This page is also a proposal during wiki population for a standardized set of units to use on pages. Please use the talk page to discuss if different units exist.
Base units[edit | edit source]
Time[edit | edit source]
The base unit of time is a second, or
s. 60 seconds is 1 minute, 60 minutes is 1 hour, obviously.
The duration of 1 day in Satisfactory is 50 minutes, consisting of a 45-min daytime and 5-min nighttime.
Item throughput[edit | edit source]
Item transportation, production and consumption rate is measured in
items per minute (items/min or ipm), also
parts per minute (ppm). By default, per minute values are displayed in game, with the exception of fuel burn time in generators, where the burn duration of one item in seconds is shown instead.
Fluid volume[edit | edit source]
The volume of Fluids is measured in cubic meters,
m3. Internally, liters are used instead, and to the player, 0.01 m3 is the smallest amount of fluid displayed (= 10 liters).
Fluid flow rate[edit | edit source]
The flow rate of Fluids is measured in cubic meters per minute,
m3/min. Some buildings even indicate direction, with positive values showing inflow and negative values for drainage.
Head lift[edit | edit source]
Head lift is measured in unnamed units, where one unit of head lift equals to 1 meter. It indicates how high a fluid can be pushed up without its flow rate being reduced below maximum, until stopping entirely.
Speed[edit | edit source]
Vehicle speed is measured in kilometers per hour,
km/h or kph. This can be converted to meter/sec by dividing it by 3.6.
Power[edit | edit source]
Power, or rate of energy flow is measured in Megawatts, or
MW, which is equal to 1,000,000 Watts. This unit is used to measure either building's power production or consumption, as well as equipment or vehicle's fuel burning rate.
Larger amounts of power can be displayed with other prefixes, such as 1,000 MW = 1 GW, and 1 TW = 1,000 GW = 1,000,000 MW. The smallest amount of power both displayed and used in-game is 0.1 MW, which is how much all powered machines consume while their Indicator Light is red or yellow.
Fuel energy[edit | edit source]
Every type fuel has a
MJ value which determines how long it is burned in a generator or a vehicle. For example, one piece of Coal has 300 MJ, and one Coal Generator provides up to 75 MW at 100% clock speed. Generators scale their production based on how much power is being consumed, e.g. when that generator would be connected to a network where 25 MW is being consumed, it would burn 3 times as slow. One piece of Coal would, therefore, last for 300/25 = 12 seconds at this power usage. If power usage increased all the way to 75 MW (maximum capacity), it would last 300/75 = 4 seconds. Exceeding capacity causes a power trip.
For fluid fuels, the MJ value is for one cubic meter.
Derived units[edit | edit source]
Belt speed[edit | edit source]
Not to be confused with belt throughput, or item flow rate (see above).
To measure belt speed, build a 48-meters long straight belt (8 Foundations) and measure the time taken to transport the player from one end to the other. Divide the distance (48 m) by the time and you got the speed in meters per second,
m/s. You can convert it into km/h by multiply it with 3.6.
Higher accuracy measurement can be achieved with longer belts, by chaining multiple belts in a straight line.
Crafting cycle energy[edit | edit source]
Similar to fuel energy, the
MJ required to complete one crafting cycle or to produce one item of that crafting cycle can be calculated using
building power consumption * crafting cycle duration, e.g. a building consuming 30 MW and completing one production cycle every 5 seconds consumes 150 MJ per crafting cycle, which equals to half of a piece of Coal being burned in a Coal Generator. If that crafting cycle yields 1 item, it cost 150 MJ, if two items 75 MJ etc.
Take note as idling buildings constantly consume 0.1 MW while not completing any crafting cycles.
Power efficiency[edit | edit source]
Power efficiency is measured in percentage
%. It is calculated by dividing the net power by gross power.
The gross power is the total amount of power produced by a power generating setup. Net power is gross power minus the internal power consumption used to run the setup, which includes Miners, Water Extractors, Pipeline Pumps etc.
