What is the Difference between Relative Humidity and Absolute Humidity?
When talking about humidity, you might have heard of two terms: relative humidity (RH) and absolute humidity (AH). While they’re related, they measure different things. Let’s break it down:
What is Relative Humidity (RH)?
Relative humidity is the ratio of the amount of moisture in the air to the maximum amount of moisture the air can hold at a given temperature. It’s expressed as a percentage, with 0% being extremely dry and 100% being completely saturated.
For example, if the air contains 10 grams of water vapor per cubic meter and the air can hold 20 grams per cubic meter at that temperature, the relative humidity would be 50%. This means the air is half-saturated with water vapor.
What is Absolute Humidity (AH)?
Absolute humidity, on the other hand, measures the amount of water vapor present in the air, usually in grams per cubic meter (g/m3). This value doesn’t depend on the air’s temperature or capacity to hold moisture.
In our previous example, the absolute humidity would be 10 g/m3, which is the actual amount of water vapor in the air.
Key Differences
- Relative humidity is a percentage, while absolute humidity is a measure of the actual amount of water vapor.
- Relative humidity depends on temperature, while absolute humidity does not.
- Relative humidity is used to predict condensation, while absolute humidity is used to measure the moisture content of the air.
