What this tool does
Wind chill describes how fast moving air pulls heat from bare skin, which is why 2 °C with a stiff breeze feels close to −3 °C. The standard formula applies below 10 °C and above 4.8 km/h of wind; outside that range it stops being meaningful.
Formula
WCT = 13.12 + 0.6215T − 11.37v^0.16 + 0.3965T·v^0.16
