Humidity units#
Humidity is represented in relative humidity units (rh or Hr). Relative humidity is the most common unit for expressing humidity levels. It represents the amount of water vapor in the air as a percentage of the maximum amount of water vapor the air can hold at a given temperature and pressure.
Relative humidity values range from 0% (completely dry air) to 100% (saturated air, where the air cannot hold any more moisture).
You can choose between two types of relative humidity units:
rH (default unit) |
