Universal and Individual Gas Constants - Engineering ToolBox

The Individual Gas Constant - RThe Universal Gas Constant - RuThe Molecular Weight of A Gas MixtureThe Universal Gas Constant - Ru - in Alternative UnitsThe Individual Gas Constant depends on the particular gas and is related to the molecular weight of the gas. The value is independent of temperature. The induvidual gas constant, R, for a gas can be calculated from the universal gas constant, Ru (given in several units below), and the gas molecular weight, Mgas: R = Ru/Mgas In the imperial system the most common units for the individual gas constant are ft lb/slug oR. In the SI system the most common units are J/kg K. Unit conversion: 1 J/kg K = 5.97994 ft lb/slug °R, and 1 ft lb/slug °R = 0.167226 J/kg K.
