WebIt is equivalent to the Boltzmann constant, except that the latter is expressed in units of energy per kelvin per particle. Denoted by the symbol R, the value of the gas constant is: R = 8.314472(15) J · K-1 · mol-1. The two digits in parentheses indicate the uncertainty (standard deviation) in the last two digits of the value. The molar gas constant (also known as the gas constant, universal gas constant, or ideal gas constant) is denoted by the symbol R or R. It is the molar equivalent to the Boltzmann constant, expressed in units of energy per temperature increment per amount of substance, i.e. the pressure–volume product, rather … See more From the ideal gas law PV = nRT we get: $${\displaystyle R={\frac {PV}{nT}}}$$ where P is pressure, V is volume, n is number of moles of a given substance, and T is temperature.
