The gas constant is calculated from R R u/M, where R u 8.31447 kJ/kmol·K and Mis the molar mass. Source:K. A. Kobe and R. E. Lynn, Jr., Chemical Review52 (1953), pp. 117–236; and ASHRAE, Handbook of Fundamentals(Atlanta, GA: American Society of Heating, Refrigerating and Air-Conditioning Engineers, Inc., 1993), pp. 16.4 and 36.1. 908
In SI units the value of the gas constant, R, is: R =8.314510 Pa m3 K-1 mol-1 = 8314.510 Pa L K-1 mol-1 = 0.08314510 bar L K-1 mol-1. This table gives the appropriate value of R for use in the ideal gas equation, PV = nRT, when the variables are expressed in other units.
