 The total count of the ore units output from a [[Centrifuge]] always equals the mass in grams of the mix put in. This is '''not faithful'''<sup>[verification needed]</sup>, because all ores in the game explicitly include impurities. The implication is that the Centrifuge somehow reintroduces the original impurities, and in fact this can be exploited to create those impurities from nothing, if you find them useful.

-''Stationeers'' measures temperature on two scales.

Fluids in enclosed spaces or in the atmosphere are measured in '''degrees Celsius''' (°C), where 0°C is the freezing point of water at standard atmospheric pressure (101.325 kPa). One kelvin is exactly equal to one degree Celsius, so you can easily convert from K to °C by subtracting '''273.15'''.

-''Stationeers'' clearly models heat conduction in general. For example, a Pipe will gradually exchange heat with its surrounding matter to reach equilibrium, and this exchange rate is greatly increased by adding a [[Pipe Radiator]]. It also models the reality that forcibly "pumping" heat from one volume to another (e.g., with an [[Kit (Atmospherics) Air Conditioner|Air Conditioner]] or an [[EVA Suit]]) requires the use of energy, and also that excess heat is not simply destroyed in this process—it still has to be disposed of somehow.
