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


specific gas constant formula

\(\large{ R = \frac{ R^* }{ MW } }\) 


 Units English Metric
\(\large{ R }\) = specific gas constant \(\large{\frac{lbf-ft}{lbm-R}}\) \(\large{\frac{J}{kg-K}}\)
\(\large{ MW }\) = molecular weight \(\large{\frac{lbm}{lbmol}}\) \(\large{\frac{kg}{kmol}}\)
\(\large{ R^* }\) = universal gas constant \(\large{ \frac{lbf-ft}{lbmol-R} }\) \(\large{ \frac{J}{kmol-K} }\)
