# Wind Chill Temperature Calculation

Wind chill temperature conversion calculator. This tool converts temperature and wind speed into wind chill temperature in Celsius or Centigrade (°C) and Fahrenheit (°F).

Wind chill temperature is only defined for temperatures at or below 50 °F (10 °C) and wind speeds above 3 mph (4.8 km/h, 2.6 kn, or 1.3 m/s).

Weather Wind Chill Temperature
Wind chill temperature (also called wind chill or wind chill factor) is how cold people feel when they are outside with skin exposed to the wind and cold. It measures the cooling effect of wind on air temperature. As the wind increases, it draws heat from your body, which reduces skin temperature and makes you feel much colder than the temperature indicated by a thermometer. Wind chill temperature is calculated using a combination of air temperature and wind speed.

To calculate wind chill temperature in Celsius or Centigrade (°C) scale, use the following formula:
Wind Chill Temperature (in °C) = 13.12 + 0.6215×T + 11.37×S⁺⁰·¹⁶ + 0.3965×T×S⁺⁰·¹⁶
where T is the air temperature in °C, and S is the wind speed in kilometer per hour (km/h).

To calculate wind chill temperature in Fahrenheit (°F) scale, use the following formula:
Wind Chill Temperature (in °F) = 35.74 + 0.6215×T + 35.75×S⁺⁰·¹⁶ + 0.4275×T×S⁺⁰·¹⁶
where T is the air temperature in °F, and S is the wind speed in mile per hour (mph).

Do you know?
Why is it colder at the top of Mount Everest than at the sea level?
You may think that it would be hotter (higher temperature) at the top of the world's highest mountain since the spot is closer to the Sun. Actually, it is cold at the top of Mount Everest because the air is thinner, with fewer air particles, at higher elevations. Temperature is affected by the amount of particles in an environment.
