Humidity of air refers to the amount of water vapor present in the atmosphere. It’s a key component of weather and climate, influencing factors such as temperature, precipitation, and the formation of clouds. Humidity is a crucial factor in human comfort, as it affects how hot or cold we perceive the temperature to be.
Absolute humidity represents the actual mass of water vapor present in a unit volume of air. It’s typically expressed in grams of water vapor per cubic meter of air (g/m³).
The formula to calculate absolute humidity is:
Where:
- Mass of water vapor (in grams)
- Volume of air (in cubic meters)
Absolute humidity is a straightforward measure of the amount of water vapor in the air and is used in various applications such as meteorology, industrial processes, and indoor air quality monitoring.
