Як розрахувати Wind Chill Calculator
Що таке 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.

- 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)
