Relative humidity definition

Relative humidity means the amount of moisture in the air relative to the amount that would be present if the air were saturated.
Relative humidity means the amount of water vapor present in the atmosphere expressed as the percentage of maximum that could be present at the same temperature
Relative humidity means the amount of water vapor present in air expressed as a
