Calculate the dew point in celsius with this Dew Point Calculator. This calculator uses the Magnus formula to calculate the dew point when the temperature range is between -45 and 60 degrees celsius. Assuming no changes in air pressure.

To calculate the Dew Point with the Magnus Dew Point formula:

RH = Relative Humidity (in percent)

T = Temperature (in Celsius)

Example: When the ambient temperature (in celsius) is 50 degrees,
relative humidity is 90%, the approximate dew point is:

Approximate Dew Point = 47.90 Degrees Celsius
