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 percent… ...

To convert between the dew point and relative humidity, several approximations have been proposed over the last 200 years, but they all require a calculator or mathematical tables, and most ...

So, what is the difference, if there really is one? To find out, let’s dive into what dewpoint is and what relative humidity is. Dewpoint is a more direct measure of moisture in the air.

The heat index, or apparent temperature, combines air temperature and humidity to indicate how hot it feels to the body. High humidity slows sweating, the body's natural cooling system, making ...

One of the most traditional and widely used measures of humidity is the wet bulb temperature. This value provides insight into how saturated the air is and is essential for calculating other ...
