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 ...

AT the recent Institute of Physics Conference at Leeds, I communicated a rule which I have found useful for calculating the relative humidity direct from readings of the ventilated wet- and dry-bulb ...

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 ...

SYRACUSE, N.Y. — Central New York is no stranger to high heat and humidity, but where does it come from and why does the humidity make it feel hotter? I'll explain how to calculate the heat index or ...

It is a number that represents how much water vapor is present now, with the amount at which water vapor saturates at that temperature taken as 100%.Therefore, even at the same 50%, the amount of wate ...

MIKE MOSS SAYS: Julia, I'm assuming you're asking about relative humidity (RH), the one (given in percent) that we typically show on air, although we prefer to track moisture in the air by way of the ...
