Trust is good. Measuring is better!

Humidity calculator for relative humidity, dew point, water vapor content and much more.

With the DKS humidity calculator, the parameters volume fractions trace moisture [ppmV], relative humidity RH [in %] and the dew point temperature Tdp [in °C] in the range -70 to +100 °C can be approximately converted. The maximum error is around 0.3%.

You will also receive information on:

  • Absolute humidity ρW (in g/m³)
  • Vapor pressure pW (in hPa/mbar)
  • Saturation vapor pressure pWS (in hPa/mbar)
  • Mixing ratio X (in g/kg)
  • Water vapor content (in g/m³)
  • Enthalpy h (in kJ/kg)
  • Mass fractions ppmW

Quick start Guide
