Gas constant - Wikipedia
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, rather than energy per temperature increment per particle.

Universal gas constant | Definition, Value, Units, & Facts - Britannica
universal gas constant, (symbol R), fundamental physical constant arising in the formulation of the ideal gas law. For an ideal gas (approximated by most real gases that are not highly compressed or not near the point of liquefaction), the pressure P times the volume V of the gas divided by its absolute temperature T is a constant.
Chemistry Definition of Gas Constant (R) - ThoughtCo

14.3: The Ideal Gas Law - Chemistry LibreTexts
R is a constant called the gas constant. The ideal gas law is what is called an equation of state because it is a complete description of the gas's thermodynamic state. No other information is needed to calculate any other thermodynamic variable, and, since the equation relates four variables, a knowledge of any three of them is sufficient.
