Formula
Variables
- T — Air temperature (°C)
- v — Wind speed (km/h)
Worked example
With air temperature = -5 °C, wind speed = 30 km/h, the calculator gives wind chill ≈ -12.99672 °C.
Frequently asked questions
What is the wind chill calculator used for?
Find how cold the wind makes the air feel. It helps with questions such as “feels like in winter”, “frostbite risk”, “windy cold temperature”.
What is the formula for the wind chill calculation?
Wind chill (°C) = 13.12+0.6215 × T-11.37 × v^0.16+0.3965 × T × v^0.16. Here T is air temperature (°C), v is wind speed (km/h).
What inputs do I need for the wind chill calculator?
You need air temperature in °C, wind speed in km/h. Each field is pre-filled with a typical example so you can see how the result responds as you edit the numbers.
How do I use the wind chill calculator?
Type values into the input fields. Results and the chart update instantly. Use Reset to restore the example values, Copy results to paste them elsewhere, or Share to copy a link that preserves your inputs.
Is the wind chill result exact?
Calculations use standard formulas and double-precision arithmetic, then display about seven significant figures. Real-world measurements carry uncertainty, so treat results as estimates unless your inputs are exact.
