__Formula__

`TD =243.04*(ln((RH)/100)+((17.625*T)/(243.04+T)))/(17.625-ln((RH)/100)-((17.625*T)/(243.04+T)))`

where

TD → Dew Point in Celsius

T → Temperature in Celsius

RH → Relative Humidity

Online Relative Humidity (RH) calculator to find the amount of moisture (water vapor) in the atmosphere or air, by using the dew point & temperature of air.

Relative Humidity often abbreviated as RH, is the quantity which represents the amount of water vapor in the atmosphere or air. It is often represented in percentage. The ideal relative humidity level is between 50% to 60%, however, the value becomes volatile based on the temperature. Human discomfort will arise when the relative humidity is getting very low. To find the amount of water vapor (moisture) in the air, users can utilize the above formula for paperwork calculation or use this relative humidity calculator with the known input values of atmospheric temperature and dewpoint of air. This calculator works well with input values in either degrees Fahrenheit or degrees Celsius scale.
