Wind Chill Calculator

The wind chill temperature can be calculated from real temperature and wind speed. This information is particularly useful for rather low temperatures, below about 10°C, it is a subjective value for the cold sensation. The stronger the wind, the stronger the perceived cold. The humidity does not play a role in the perceived cold temperature, but it does in heat, see the heat index.
Please enter the wind speed and one of the two temperatures, the other temperature will be calculated. The wind speed can be specified in kilometers per hour or in meters per second.

The formula for the calculation is w = 13.12 + 0.6215*t - 11.37*v^0.16 + 0.3965*t*v^0.16
w = wind chill in degrees Celsius, v = wind speed in kilometers per hour, t = real temperature in degrees Celsius

Example: at 5 degrees Celsius and a wind speed of 20 kilometers per hour, the perceived temperature is about 1 degree Celsius.

Physics commonly uses SI units. Here is a calculator to convert lengths, temperature, pressure, speed and other units.
