WebSep 11, 2016 · Using equation 2 for absolute humidity, the absolute humidity is 0.0103 g/L. Another measurement unit of importance is relative humidity, usually measured as a percent. Relative humidity is a measure of how much water vapor can be contained in a carrier gas, such as air before saturation occurs and condensation ensues. WebThe basics Put simply, relative humidity (RH) is a measure of the water vapor content of air. More explicitly, it is the amount of water vapor present in air expressed as a percentage (%RH) of the amount needed to achieve saturation at the same temperature. RH is strongly proportional to temperature and highly sensitive to temperature changes.
