litre is the si unit of measurement for volume.
what is the si unit of measurement for volume?
litre
the original french metric system used the litre as a base unit. the word "litre" is derived from an older french unit, the "litron", whose name came from greek — where it was a unit of weight, not volume — via latin, and which equalled approximately 0.831 litres. the litre was also used in several subsequent versions of the metric system and is accepted for use with the si, although not an si unit — the si unit of volume is the cubic metre (m). the spelling used by the international bureau of weights and measures is "litre", a spelling which is shared by almost all english-speaking countries. the spelling "liter" is predominantly used in american english.

the gas constant occurs in the ideal gas law, as follows:





























where "p" is the absolute pressure (si unit pascals), "v" is the volume of gas (si unit cubic metres), "n" is the amount of gas (si unit moles), "m" is the mass (si unit kilograms) contained in "v", and "t" is the thermodynamic temperature (si unit kelvins). "r" is the molar-weight-specific gas constant, discussed below. the gas constant is expressed in the same physical units as molar entropy and molar heat capacity.

from the ideal gas law "pv" = "nrt" we get:
