True vapor pressure refers to the pressure exerted by a vapor in thermodynamic equilibrium with its liquid (or solid) phase at a given temperature. It represents the tendency of a substance to evaporate and is specific to a particular temperature. True vapor pressure is typically measured in units such as millimeters of mercury (mmHg) or pascals (Pa).
