What is dew point?

Dew point is the temperature gas gets saturated with water which then results in the formation of dew or fog. Our Michell industrial dew-point calculator facilitates swift and effortless humidity calculations and parameter conversions for engineers. It is designed to be used as a standalone tool or combined with a hygrometer.

The dew-point calculator can calculate humidity values at different pressures, calculate parameters unavailable on a particular instrument, or convert previously measured data to alternative parameters.

Users can calculate multiple parameters, including dew-point temperature, frost-point temperature, relative humidity, absolute humidity, parts per million (volume), parts per million (weight), mixing ratio, wet bulb temperature, water vapor pressure & saturation vapor pressure, and enthalpy.

The dew-point calculator uses the Sonntag formula for water vapor pressure as seen in the British Standard 1339:1, 3.2.2. Users can customize the settings to change which parameters are shown and alter the order to ensure complete ease of use.

Alternatively, you can use our pressure dew point conversion chart over ice and water. The tables include conversions using the Sontag and Wexler methods.
