Web28 feb. 2024 · Humidity is, in general, a measure of water vapor in the air. Meteorologists typically describe water vapor in the atmosphere in two different ways: absolute humidity and relative humidity. Dew point is an absolute measure and helps us understand how muggy and humid it feels outside. Imagine: You take a nice, long, hot shower. WebHumidity can be measured in two ways: Absolute humidity is the amount of moisture present in a particular volume of air and is typically measured in g/kg. Relative humidity (RH) is the relationship between the actual amount of moisture present and the maximum amount the air could contain. This is always measured as a percentage.
