The ratio of the mass of water to the total mass of a moist air sample. It is usually expressed as grams of water per kilogram of dry air (gw/kgda) or as pounds of water per pound of dry air (lbw/lbda)

Water vapor within a given space
* Absolute humidity: The mass of water vapor in a specific volume of a mixture of water vapor and dry air.
* Relative Humidity: Ratio of the partial pressure or density of water vapor to the saturation pressure or density, respectively, at the same dry-bulb temperature and barometric pressure of the ambient air. Ratio of the mole fraction of water vapor to the mole fraction of water vapor saturated at the same temperature and barometric pressure. At 100% relative humidity, the dry-bulb, wet-bulb, and dew-point temperatures are equal

The process of adding moisture to air or gases
