Dew Point Calculator (Celsius)

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.

Humidity: %
Fill in the temperature and humidity to determine the approximate
dew point.

What is the Magnus Dew Point Formula?

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

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
