The gas constant occurs in the ideal gas law: where P is the absolute pressure, V is the volume of gas, n is the amount of substance, m is the mass, and T is the thermodynamic temperature. Rspecific is the mass-specific gas constant. The gas constant is expressed in the same unit as molar heat.
In the imperial system the most common units for the individual gas constant are ft lb/slug o R . 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.
