The dewpoint calculator computes a dewpoint based on the surface temperature and altitude of the cloud base.

INSTRUCTIONS: Choose units and enter the following:

  • (CB) Cloud Base
  • (ST) Surface Temperature

dewpoint (DP): The temperature is returned in degrees Fahrenheit.  However, these can be automatically converted to compatible units via the pull-down menu.

The Math / Science

This is a basic formula to calculate dewpoint from the elevation of cloud base (feet) and the surface temperature (Celsius).  This information is meant for illustrative purposes only.
