WebUnits of measurement. In the International System of Units, the energy efficiency in transport is measured in terms of metre per joule, or m/J.Nonetheless, several conversions are applicable, depending on the unit of distance and on the unit of energy. For liquid fuels, normally the quantity of energy input is measured in terms of the liquid's volume, such … Web6 dec. 2024 · The ideal gas equation is: PV=nRT P V = nRT where R is a constant known as the ideal gas constant. In SI (metric) units, the value of this constant is 8.314 joules per mole Kelvin. Pressure is constant : Rearranging this equation to isolate volume, you get: V=\frac {nRT} {P} V = P nRT
