# Specific Gas Constant

Specific gas constant, abbreviated as R, deals with the universal gas constant which is equal to 8.314 joules per Kelvin.

- See specific gas constant value.

## Formulas that use Specific Gas Constant

\(\large{ R = \frac{ R^* }{ MW } }\) | |

\(\large{ R = \frac {p }{\rho \; T} }\) | (ideal gas law) |

### Where:

\(\large{ R }\) = specific gas constant

\(\large{ \rho }\) (Greek symbol rho) = density

\(\large{ MW }\) = molecular weight

\(\large{ p }\) = pressure

\(\large{ T }\) = temperature

\(\large{ R^* }\) = universal gas constant ( 8314 J/kmol-K )
