Wind chill is how cold the air actually feels on exposed skin once moving air is factored in, because wind strips away the thin insulating layer of warmed air around the body and speeds up heat loss. This wind chill calculator uses the current U.S. National Weather Service formula (adopted in 2001): in imperial units, WC(°F) = 35.74 + 0.6215T − 35.75V^0.16 + 0.4275T·V^0.16, with T the air temperature in °F and V the wind speed in mph; the metric version, WC(°C) = 13.12 + 0.6215T − 11.37V^0.16 + 0.3965T·V^0.16, uses °C and km/h.
As a worked example, an air temperature of 20 °F with a 15 mph wind feels like about 6 °F — roughly 14 degrees colder than the thermometer reads. Raise the wind and the chill deepens, but with diminishing returns, since the V^0.16 term flattens out at high wind speeds. The calculator shows the feels-like temperature, how much colder that is than the actual air, and a table of wind chills across a range of wind speeds so you can see the trend.
The formula is only defined for cold, breezy conditions — at or below 50 °F (10 °C) and winds above about 3 mph (5 km/h) — so above those the "feels like" simply equals the air temperature. Beyond comfort, wind chill matters because it governs how fast exposed skin can freeze: the tool flags frostbite risk, which becomes serious once the wind chill drops below about −18 °C (0 °F) and can freeze skin in under 30 minutes in extreme cold.

It is defined for temperatures at or below 50 °F (10 °C) and winds above about 3 mph (5 km/h). Above those, wind has little cooling effect and the "feels like" equals the air temperature.
