Question

relative humidity has no unit​

Answer 1

Answer:

Humidity is defined as the ratio between the vapor pressure of water vapor in the air to the vapor pressure at saturation. ... However, there is no official or special SI unit for humidity measurement.

Answer 2

Answer:

Explanation:

Relative humidity (RH) is the ratio of the partial pressure of water vapor to the equilibrium vapor pressure of water at a given temperature. Relative humidity depends on temperature and the pressure of the system of interest. The same amount of water vapor results in higher relative humidity in cool air than warm air.
