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 ...

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 ...

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 ...

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 ...

Relative humidity and dew point both give us an idea of the amount of moisture in the atmosphere; however, only dew point is a true measurement of the atmospheric moisture. Relative humidity is ...

If you’re looking for a single number that’ll help you best determine whether or not it’s muggy outside, you’ll want to give this a read. On Tuesday afternoon, it was 71 degrees with a 56 degree ...

Dew point/relative humidity questions come up fairly often and this is a good one. Water vapor in the atmosphere is pretty important for deep-sky observing and photography. The atmosphere can only ...
