A Wind Chill Calculator is a tool that tells you how cold it feels outside due to wind. It does not change the actual air temperature, but it shows how your body feels when wind removes heat from your skin. When wind blows, it takes away the thin layer of warm air around your body. This makes you feel colder faster. The Wind Chill Calculator uses two main things: air temperature and wind speed. When the temperature is low and wind speed is high, the wind chill value becomes much lower. For example, if the air temperature is 0°C and the wind speed is strong, it may feel like -10°C or even colder. The Wind Chill Calculator helps show this feeling in numbers.
