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 (weight) of water vapor per kilogram, the higher the absolute humidity. . Humidity refers to the amount of moisture (water vapor) in the surrounding air.. Relative.
