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.
Takon kang asring diajukake
Apa kang diarani wangun dhasar?
Ing taun 2001, NWS ngenani unit imperial WC = 35.74 + 0.6215T − 35.75V^0.16 + 0.4275T·V^0.16, kanthi T ing °F lan V ing mph. iku modeling panas kang ilang saka kulit kang ora diwadhahi nalika angin ngrusak lapisan panas kang tipis ing sakiwa-tengené awak.
Apa kang dadi sebabé?
Ing mangsa panas, suhu rata-rata ing wewengkon iki 50 °F (10 °C) lan angin bisa tekan 3 mph (5 km/jam). Sawisé iku, angin ora bisa ngresiki lan "rasa kaya" padha karo suhu udara.
Apa kang bisa dadi sebabé?
Nalika suhu angin mudhun ing ngisor −18 °C (0 °F), frostbite dadi risiko, lan ing ngisor −28 °C (−19 °F) kulit sing ditemokake bisa beku ing 30 menit utawa kurang — luwih cepet ing angin sing luwih ekstrim.
Apa kang dadi sebabé, apa ora?
Mung barang- barang urip, kang adhem tinimbang udara. Angin- angin ngukur kacepetan awak kang adhem ngalami panas, mula iku ndadèkaké wong lan kéwan rasa adhem, nanging ora bisa ngresiki obyek kaya mobil utawa pipa banyu ing ngisor suhu udara nyata.
Nanging, apa ora bisa digawé supaya ora ana panas ing banyu?
Formula iki nggunakake kecepatan angin kanggo daya 0. 16, kang mundhak kanthi cepet ing wiwitan lan banjur rata. Nalika tekan 5- 15 mph suhu bakal mudhun, nanging nalika tekan 40- 50 mph suhu bakal mudhun.
Ing basa Inggris, suhuné diukur ing °F/mph lan °C/km/h.
Ya. Pilih imperial kanggo ngetik °F lan mph utawa metrik kanggo °C lan km/h, lan iki bakal nglakokaké persamaan NWS sing cocog. Ambang frostbite ditimbang ing skala metrik internal supaya loro sistem unit setuju.
Temperature punika dipunwastani suhu ingkang dipuntingali.
Ing dhuwur 50 °F (10 °C), utawa nalika angin kurang saka3mph (5 km/h), angin ora bisa ngresiki lan suhu sing dirasa padha karo suhu udara - mula kalkulator bakal bali kanthi notasi tinimbang angka sing luwih cilik ing kahanan iki.
