Humidity Calculator

The humidity calculator offers a comprehensive selection of humidity units. High and low humidity ranges are covered. It facilitates calculations with extremely dry gases containing only parts per billion (ppb) moisture content - which is, of most relevance to sectors such as semiconductor industry. At the other end of the scale, it is capable of calculations involving very high concentrations of water vapour - such as in paper production and certain metallurgical processes. Parameters included on the online calculator: •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
