Air humidity measurements are based on the water content of the air, expressed as volume percentage:

Relative Humidity = percentage of saturation at a given temperature

Absolute Humidity = percentage of water in the air, regardless of saturation or temperature.

The humidity that is talked about in weather reports, is relative humidity.
