At standard temperature and pressure one mole of any ideal gas occupies the same volume, so moles and liters convert with a single constant. This calculator uses classic STP — 0 °C and 1 atm — where Vm = 22.414 L/mol (0.02241396954 m³/mol). Note that IUPAC's newer 100 kPa definition of STP gives 22.711 L/mol instead, so always check which convention a problem assumes.
