Michell's moisture and humidity calculator app for iPhone and Android


Michell Instruments has launched a mobile app version of its humidity calculator to enable fast calculations of trace moisture, moisture in liquids and relative humidity. The app, which is available to download for free on iTunes and Android market, is based on Michellís popular moisture and humidity slide rule. The calculator is a valuable tool for anyone working with processes involving moisture control or analysis.

The moisture calculator app includes the following parameters:
  • Relative humidity
  • Absolute humidity, g/m3
  • Mixing ratio, g/Kg
  • Moisture content, ppmV in gases
  • Moisture content, ppmW in liquids
  • Dew point, °C, and vapour pressure


  • The application allows for easy calculations and conversions between units of moisture content in parts per million (ppm), dew point, relative humidity and moisture in liquid.

    The humidity calculator offers a comprehensive selection of humidity units with high and low humidity ranges are covered. It facilitates calculations with extremely dry gases containing only parts per billion (ppb) moisture content. At the other end of the scale, it is capable of calculations involving very high concentrations of water vapor - such as in paper production and certain metallurgical processes.

    Pressure and temperature compensation is incorporated, where relevant, for each unit conversion. To complete the comprehensive coverage of the calculator, metric to imperial conversions are provided for temperature and pressure.

    Visit iTunes or Android Market to download for free.
