At a temperature of -20 ° C, the absolute air humidity is 0.55 g / m³. Calculate the relative humidity of the air.

At a temperature of -20 ° C, the absolute humidity of the air can be equal to 1 g / m³, but in reality it is 0.55 g / m³.
We write down the ratio of the actual content of water vapor in the air to the maximum possible for this temperature:
(0.55 / 1) * 100 = 55% – relative humidity.
