What type of humidity measures actual moisture content regardless of temperature?

Absolute humidity measures the actual moisture content in the air, expressed as the mass of water vapor per unit volume of air, typically in grams per cubic meter. This measurement is independent of temperature and pressure, which is why it provides a clear understanding of the total amount of moisture present in the air at any given moment. This contrasts with relative humidity, which is a percentage that indicates how much moisture is in the air relative to the maximum amount of moisture the air can hold at that temperature. Specific humidity is also related to the water vapor content but takes into account the total mass of air, rather than just the volume, and vapor pressure refers to the pressure exerted by water vapor in the air, which can vary with temperature as well. Thus, absolute humidity is the most straightforward measure of moisture content regardless of temperature conditions.
