Difference between Humidity, Absolute Humidity & Relative Humidity?
Humidity
Humidity is the quantity of water vapour present in the atmosphere.
Absolute Humidity
Absolute humidity is the mass of water vapour
contained in a sample of air. It is usually expressed in grams per cubic metre (gm/m3)
Relative Humidity
Relative humidity is the percentage ratio of the
actual water vapour contained in a given sample of air, to the maximum quantity of water vapour that the sample can hold at that temperature
RH % = (Present quantity of water vapour ÷ Max. possible at that temperature) X 100
