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
