Thermodynamics: An Engineering Approach [9th ed

Therefore, the common reading of 32.0 psi (2.25 kgf/cm2) indicates a pressure of 32.0 psi above the atmospheric pressure. At a location where the atmospheric pressure is 14.3 psi, for example, the absolute pressure in the tire is 32.0 + 14.3 = 46.3 psi. In thermodynamic relations and tables, absolute pressure is almost always used.
