WebAbsolute Humidity. Absolute humidity, which describes air’s water content, is used to measure the weight of water vapour per unit volume of air. The absolute humidity unit is given as g.m -3 which is units of grams of water vapour per cubic metre of air. Since other factors constantly affect absolute humidity, the results are less useful. WebRelative humidity (RH) is another measure of water vapor in the atmosphere, although we must be careful when using it because a low relative humidity may not mean a low water vapor mixing ratio (i.e., at high temperatures) and a high relative humidity might still be quite dry air (i.e., at low temperatures). birthing on country cre
