The Gas Constant, R, in Various Units

R is the gas constant in the ideal gas equation




pV = nRT



R is related to the Boltzmann constant, k, by



R = k _ NA



where k = 1.3806 x 10-23 J K-1, and NA = 6.022 x 1023 mol-1



R with different units



8.31451 J K-1 mol-1



8.20578 x 10-2 L atm K-1 mol-1



8.31451 x 10-2 L bar K-1 mol-1



8.31451 Pa m3 K-1 mol-1



62.364 L Torr K-1 mol-1



1.98722 cal K-1 mol-1
