The ratio of the amount of water vapor in the air to the amount of water vapor needed to reach saturation at a given temperature is called **relative humidity**. It is usually expressed as a percentage.
Mathematically, relative humidity (RH) can be defined as:
\[
\text{Relative Humidity (RH)} = \left( \frac{\text{Actual water vapor content}}{\text{Saturation water vapor content}} \right) \times 100
\]
Where:
- **Actual water vapor content** is the mass of water vapor present in a given volume of air.
- **Saturation water vapor content** is the maximum amount of water vapor that can be present in the air at a specific temperature before condensation occurs.
Relative humidity provides a measure of how close the air is to being saturated with moisture. For example, an RH of 100% means the air is fully saturated with water vapor, while an RH of 50% indicates that the air holds half of the moisture it could potentially hold at that temperature.
