Relative humidity is the ratio of the partial pressure of water vapour to the saturation vapour pressure of water at the same temperature. Relative humidity depends on temperature and the pressure.
Very roughly speaking, it is a ratio of the amount of water vapour in the air compared to the total amount of water vapour that it possible for that air to contain.

How do relative humidity and mixing ratio differ?
Relative humidity is the ratio of the amount of water vapor present in the air to the maximum amount the air can hold at a given temperature, expressed as a percentage. Mixing ratio, on the other hand, is the ratio of the mass of water vapor to the mass of dry air in a sample. While relative humidity is a measure of how close the air is to saturation, mixing ratio gives a direct measure of the amount of water vapor present in the air.
Which is the comparison of the amount of moisture in the air to the amount of moisture it can hold?
relative humidity
What weather factor is a hygrometer use for?
Hygrometers measure the relative humidity of the atmosphere. The relative humidity is the ratio between the present water vapor content of the air and the maximum amount of water vapor the air could hold at the same temperature. Cool air will not hold as much water vapor as warmer air. With the same amount of moisture in the air, an increase in temperature decreases the relative humidity, and if the temperature drops, relative humidity increases.
What is the abbreviation of relative humidity?
The abbreviation for relative humidity is RH.
Relationship between evaporation and relative humidity?
Evaporation is the process by which a liquid turns into a gas, while relative humidity is the ratio of the amount of water vapor present in the air compared to the maximum amount the air can hold at a specific temperature. A higher relative humidity means the air is already holding a lot of water vapor and so evaporation will be slower, while a lower relative humidity allows for faster evaporation as the air has more capacity to hold additional water vapor.
