Vapor Pressure of Water at Varying Temperatures

The following tables list values for the vapor pressure of water at varying temperatures. This data is often used with Dalton's Law to determine the pressure of a gas collected above water. Learn more.

Below the document is also a web version of the table that is searchable for screen readers. To quickly find the row for the temperature, use your screen reader's built in search to search and skip to a row by typing in temp space and the degree number, example t e m p space 10 will bring you to the 10 degree Celsius row.
