– How can humidity in the air be measured as a percentage? How much humidity is 100%?
In: 151
It is in relation to maximum saturation of the air, at which point the air mass cannot hold any more water. This can also be expressed by the Dew point, which is considering how much water is in the air mass, if you lower the air mass to that temperature it will reach maximum saturation. So a small temperature dew point spread means there is a lot of moisture in the air, where a large spread means it’s a very dry air mass.
