WebFeb 20, 2022 · For example, if your tire gauge reads 34 psi (pounds per square inch), then the absolute pressure is 34 psi plus 14.7 psi ( Patm P a t m in psi), or 48.7 psi (equivalent to 336 kPa). Definition: Absolute Pressure. Absolute pressure is the sum of gauge pressure and atmospheric pressure.
