What is the difference between humidity and relative humidity?

Absolute humidity is the measure of water vapor (moisture) in the air, regardless of temperature. It is expressed as grams of moisture per cubic meter of air (g/m3). For more info on Zehnder America, contact us today. read more

Humidity vs Relative Humidity. The Earth’s atmosphere is composed of gases which are held together by gravity. It protects the Earth and all living things therein from solar radiation. It consists of different layers with pressure, thickness, density, and mass that also varies. read more

Absolute Humidity, often just referred to as 'the humidity', is a measure of the actual amount of water vapour in a particular sample of air: measured as a partial pressure (vapour pressure/hPa or millibars); a mixing ratio (gm water vapour/kg of dry air), dew point etc. read more

Relative humidity is the percentage of the moisture against the highest possible level of moisture in the air at a specific temperature. Relative humidity is measured higher at a lower temperature because cold air holds more water vapors than the warm air. read more
