"Absolute humidity is the total mass of water vapor present in a given volume or mass of air. It does not take temperature into consideration. Absolute humidity in the atmosphere ranges from near zero to roughly 30 g (1.1 oz) per cubic metre when the air is saturated at 30 °C (86 °F). Absolute humidity is the mass of the water vapor , divided by the volume of the air and water vapor mixture , which can be expressed as: " - Mixed air humidity ratio
