You have expressed a common misconception. Relative humidity is the amount of water vapor in air divided by the maximum amount the air can contain at a given temperature, expressed as a percent.

A researcher at the Max Planck Institute for Chemistry in Mainz, Germany, has suggested a very simple formula for converting between the relative humidity and the dew point temperature without needing ...

We’ve recently received several reader requests asking us how to calculate relative humidity if the temperature and dew point are known. Relative humidity is the ratio (expressed as a percentage) of ...

The relative humidity is the percent of saturation humidity. When the relative humidity is 100%, it means the air is completely saturated with moisture. Since warmer air can hold much more water vapor ...

Air pollution is not taken into consideration. Actually, relative humidity is not directly measured. The air temperature and dew point temperature are measured, and the relative humidity is then ...

The short answer is both terms are different and describe different things about moisture in the air. The dew point is another temperature value. It is the temperature air needs to cool to become ...

When referring to the mugginess of the air, meteorologists will point to dew point rather than relative humidity. Relative humidity is indeed a measure of how much moisture is in the air relative to ...

Mike Moss: Relative humidity is not related to temperature and dew point in quite that direct a manner, although they certainly are interdependent quantities. There are some online calculators that ...
