As a percentage. It is the water vapor content of the air compared to the normal maximum content at that temperature. (For supercooled air, the humidity is more than 100% for the temperature.)

Measure of humidity?
Relative humidity and is expressed as a percentage. Absolute humidity is expressed as a concentration - mg/L. Specific humidity is a ratio of masses - water to air in a finite volume.
Is relative humidity expressed as a fraction?
It is expressed as a percentage (fraction of 100%).
How do you put the word relative humidity in a sentence?
The relative humidity is very high today. It is the fraction of water vapor in the air expressed as a percentage of the level where it condenses to a fog.
How does a meteorologist express the amount of moisture in the air?
It is called relative humidity and it is expressed in percentages.
What are humidity measurements based upon?
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.
Which is the comparison of the amount of moisture in the air to the amount of moisture it can hold?
relative humidity
Relative humidity is always expressed?
Yes. It is the percentage of the maximum water vapor content for a given temperature.
Amount of moisture in air compared to amount needed in saturation?
Relative humidity.
What is the amount of water vapor in the air compared to the amount that could be in the air at that temperature?
relative humidity
What should the low and high end for humidity temperatures for your home?
30 to 50% of Relative humidity - the relative part of relative humidity being relative to the temperature.
What is the relative humidity of the air?
The relative humidity of the air is a measure of how much moisture is in the air compared to the maximum amount of moisture the air can hold at a given temperature. It is expressed as a percentage and indicates how close the air is to reaching its saturation point.
How to Calculate actual humidity from relative humidity?
One can calculate the absolute humidity (AH) from the relative humidity (r) using three equations: (1) the equation for mixing ratio, (2) an equation for relative humidity expressed in terms of mixing ratio, and (3) the Clausius-Clapeyron equation, which relates saturation vapor pressure to temperature. The result of combining the three equations is: AH = (1324 r/T) [exp {5417.75 (1/273 - 1/T)}] where AH is expressed in grams per cubic meter, T is temperature in Kelvin, r is relative humidity (range is 0 to 1), and the relation holds true for T>273. For T<273, replace 5417.75 with 6139.81.
