A constant, equal to 8.314 joules per Kelvin or 1.985 calories per degree Celsius, that is the constant of proportionality (R) in the equation Pressure × Volume = n (number of moles) × (R) × Temperature, relating the pressure and volume of a quantity of gas to the absolute temperature.

a universal constant, R, that seems into the ideal gas legislation, (PV = nRT), produced from two fundamental constants, the Boltzman constant and Avogadro's number, (R = NAk)

(physics) the universal constant when you look at the gasoline equation: pressure times volume = R times temperature; equal to 8.3143 joules per kelvin per mole
