How to Calculate Wind Chill Calculator
What is Wind Chill Calculator?
Wind chill is the perceived decrease in air temperature felt by exposed skin due to the flow of air. Wind accelerates heat loss from the body — the faster the wind, the colder it feels, even if the actual temperature is unchanged.
Step-by-Step Guide
- 1The Environment Canada / NWS formula: WC = 13.12 + 0.6215T − 11.37V^0.16 + 0.3965TV^0.16
- 2T = air temperature (°C), V = wind speed (km/h)
- 3Only applies when temperature is below 10°C (50°F) and wind speed > 4.8 km/h
- 4Human skin temperature is used as the reference (33°C / 91°F)
Worked Examples
Input
−10°C with 30 km/h wind
Result
Feels like −20°C
Wind doubles the effective cold
Input
5°F with 20 mph wind
Result
Feels like −15°F
