 Conversions between moisture units made easy!
The Xentaur Moisture Calculator is an easy to use but powerful Windows® program that lets you convert moisture units and calculate dewpoints and partial water vapor pressures at different total pressures.
The calculator even lets you make conversions with moisture concentrations by weight, using the pre-programmed molecular weights of many frequently encontered gases or simply, manually entered molecular weights.
Unit conversions can be made using the following most populr formulas, with or without the Greenspan water vapor Enhancement factor: Goff Gratch, Clausius-Clapeyron, Hyland & Wexler, Sonntag, Magnus.
