Estimates wind chill in Fahrenheit using air temperature and wind speed in miles per hour.
How it works
Estimates wind chill in Fahrenheit using air temperature and wind speed in miles per hour.
Formula and assumptions
The standard wind-chill equation is intended for temperatures at or below 50°F and wind speeds above 3 mph. It estimates exposed-skin cooling, not actual air temperature.
Example
Use the sample values, calculate, and change one input at a time.
