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

Pressure of an Ideal Gas formula

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


 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 \(\large{ in^3 }\) \(\large{ mm^3 }\)
