ABSOLUTE HUMIDITY: Absolute humidity (expressed as grams of water vapor per cubic meter volume of air) is a measure of the actual amount of water vapor (moisture) in the air, regardless of the air's temperature.
The higher the amount of water vapor, the higher the absolute humidity. The Rotronic Humidity Handbook All you never wanted to know about Humidity and didn’t want to ask. Rotronic Instrument Corp. elizrosshubbell.com This article discusses the best ways to control relative humidity indoors for common air conditioning and heating systems, including the best humidity ranges for people, electronics, and books.

The dew point is the temperature the air needs to be cooled to (at constant pressure) in order to achieve a relative humidity (RH) of %. At this point the air cannot hold more water in the gas form. The heat index (HI) or humiture is an index that combines air temperature and relative humidity, in shaded areas, to posit a human-perceived equivalent temperature, as how hot it would feel if the humidity were some other value in the shade.
