Values are given in terms of temperature necessary to reach the specified pressure. Valid results within the quoted ranges from most equations are included in the table for comparison. A conversion factor is included into the original first coefficients of the equations to provide the pressure in pascals (CR2: 5.006, SMI: -0.875).

Online calculator, figures and tables with water saturation (vapor) pressure at temperatures ranging 0 to 370 °C (32 to 700°F) - in Imperial and SI Units.
Vapor Pressure Calculator. Blue fields allow input. The form below contains input fields, and read-only fields for output. Press <RETURN> or <TAB> to calculate. Accuracy: For many substances, vapor pressures are only poorly known; expect errors up to a few 10% of the vapor pressure value.
The vapor pressure is an indication of a liquid's evaporation rate. It relates to the tendency of molecules andatoms to escape from a liquid or a solid. Any substance with a significant vapor pressure at temperatures of about 20 to 25 °C (68 to 77 °F) is very often referred to as being volatile.
Vapor pressure is measured in the standard units of pressure.The International System of Units (SI) recognizes pressure as a derived unit with the dimension of force per area and designates the pascal (Pa) as its standard unit. [1] One pascal is one newton per square meter (N·m −2 or kg·m −1 ·s −2).. Experimental measurement of vapor pressure is a simple procedure for common pressures ...
