Dew Point Calculator

Our Dew Point Calculator is an easy-to-use tool that allows you to determine the dew point based on ambient temperature and relative humidity. The dew point is the value to which air must be cooled in order for the water vapor it contains to become saturated and condense as dew, and is an important indicator in meteorology, HVAC, and many industrial processes.
Features:
This calculator is based on the Magnus-Tetens formula (Mark G. Lawrence, 2005)
It gives an uncertainty of 0.35 °C in a range between -40 °C and 50 °C.
How to Use:
Select your preferred language from the selector in the top right corner.
Enter the temperature in degrees Celsius and the relative humidity in percentage.
Choose the number of decimal places you want for the final result.
Press the "Calculate Dew Point" button and you will obtain the value of the temperature at which condensation occurs in the air.
