Explore a comprehensive table of water vapor pressure at different temperature values presented in both SI (kPa) and US customary (psi) units.
Quick Example: Vapor pressure of water at 20°C is 2.37 kPa, 0.34 PSI, 17.81 mmHg, 0.02 Bar, 0.02 atm, or 17.81 torr (from 2nd °C calculator and chart). Since we have 3 different temperature units ( Fahrenheit °F , Celsius °C , and Kelvin K ), we created 3 separate parts here.
31 lip 2024 · With this vapor pressure of water calculator, you can find the vapor pressure at a particular temperature according to five different formulas. This calculator works for the standard 0-100 °C range as well as temperatures above 100 °C and below the freezing point.
