Specific Gas Constant Value

In an ideal gas, molecules have no volume and do not interact.
 

Pressure of an Ideal Gas formula

\(\large{ p = \frac {n \;  R \;  T_a}{V} }\)

Where:

Units	English	Metric
\(\large{ p }\) = pressure	\(\large{\frac{lbf}{in^2}}\)	\(\large{Pa}\)
\(\large{ T_a }\) = absolute temperature	\(\large{R}\)	\(\large{K}\)
\(\large{ n }\) = amount of substance	\(\large{dimensionless}\)
\(\large{ R }\) = specific gas constant (gas constant)	\(\large{\frac{ft-lbf}{lbm-R}}\)	\(\large{\frac{J}{kg-K}}\)
\(\large{ V }\) = volume	\(\large{ in^3 }\)	\(\large{ mm^3 }\)
