Absolute Humidity Calculator

Your details

The ambient air temperature. Calculations work in Celsius internally; Fahrenheit is converted automatically.
degC
The percentage of water vapor in the air relative to the maximum it can hold at that temperature.

The air contains 13.803 g of water vapor per cubic metre.

  • The air holds a noticeable amount of moisture. Many people find this level mildly uncomfortable, especially during physical activity.
  • The saturation deficit is 1266 Pa - the air could absorb 1266 Pa more vapor before reaching 100% RH.
  • Specific humidity is 11.742 g of water per kilogram of moist air, useful in HVAC and aviation calculations.

Next stepYour dew point is 16.7 degC. If a surface cools to that temperature, condensation will form on it.
