Among the uses for the humidity calculator are:
- Calculating humidity values at different pressures
- Calculating parameters that are not available on a particular instrument
- Converting previously measured data to alternative parameters.
The calculator is based on the formula found in British Standard BS1339-1, enabling the user to calculate any one of the following parameters with confidence:
- Dew Point temperature
- Frost Point temperature
- Relative Humidity
- Absolute humidity
- Parts per million (volume)
- Parts per million (weight)
- Mixing Ratio
- Wet Bulb temperature
- Water Vapour Pressure & Saturation Vapour Pressure
- Enthalpy
Users can customise the settings to change which parameters are shown and alter the order, to ensure complete ease of use.
A separate natural gas moisture calculator allows calculation of water dew-points in natural gas from ppmV and absolute humidity (mg/m3, g/m3, kg/m3, lb/MMscf) and vice versa. These calculations are based on methods found in ISO 18453 and IGT Bulletin #8.
The online version of the calculator supports all major browsers (IE9+) and also works with Android, iOS and most other mobile devices.
