What is a Wind Chill Calculator?

Wind Chill Calculator is an online, no-cost device that calculates the “feels-like” temperature by marrying real-time air temperature with wind speed. Wind raises the heat-loss rate from exposed skin, so the air feels lower than the thermometer reports. Wind Chill Calculator gives you a better sense of cold conditions as they really experience, so you can better prepare for outdoor labor, travel, or leisure activities. It benefits hikers, runners, parents, builders, and anyone who reviews a weather forecast prior to going outside.

How Does the Wind Chill Calculator Work?

1. Type in the temperature in °C or °F.
2. Step wind in km/h, mph, or m/s — the calculator performs unit conversions automatically.
3. Click Calculate to find the feels-like temperature.
4. Save or copy the answer for weather reports or planning of activities.

Wind Chill Formulas

• For °F / mph (NWS, USA):
  WCF = 35.74 + 0.6215T − 35.75v^0.16 + 0.4275Tv^0.16
  (valid for T ≤ 50°F and v ≥ 3 mph)
• For °C / km/h (Environment Canada):
  WCI = 13.12 + 0.6215T − 11.37v^0.16 + 0.3965Tv^0.16  
  (valid for T ≤ 10°C and v ≥ 4.8 km/h).
