Ngenai kalkulator iki
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.

Apa tegese tembung "kaca"?
Formula NWS (2001) dina unit imperial nyaéta WC = 35.74 + 0.6215T − 35.75V^0.16 + 0.4275T·V^0.16, kalayan T dina °F sarta V dina mph.
Apa sing diarani angin?
Ieu didefinisikan pikeun suhu di handapeun 50 °F (10 °C) sarta angin di luhur 3 mph (5 km/h). Di luhur éta, angin henteu ngagaduhan efek pendinginan anu ageung sareng "rasana" sami sareng suhu udara.
Apa bisa diukur suhunya?
Nalika suhu turun ka handap -18 °C (0 °F), frostbite jadi bahaya, sarta handapeun -28 °C (-19 °F) kulit anu kabuka bisa beku dina 30 menit atawa kirang — langkung gancang dina angin anu langkung ekstrim.
Apa angin sing adhem bisa ngrusak barang, utawa mung wong?
Ngan hal- hal hirup, anu leuwih haneut ti udara. Angin anu ngalebur ngukur kumaha gancang awak anu haneut leungit panasna, jadi ngajadikeun jalma jeung sato ngarasa leuwih haneut, tapi teu bisa ngalebur objék kayaning mobil atawa pipa cai di handapeun suhu udara anu saleresna.
Apa tegese ora ana sing bisa ngganti suhune?
Formula ngagunakeun kecepatan angin ka kakuatan 0.16, anu naék dina awalna sareng teras rata. Ti 5 ka 15 mph turunna suhuna rada, tapi ti 40 ka 50 mph ngan saeutikna ngarobih éta.
Apa kalkulator iki bisa digunakake ing °F/mph lan °C/km/h?
Ya. Pilih imperial pikeun ngetik °F sareng mph atanapi metrik pikeun °C sareng km/h, sareng éta bakal nerapkeun persamaan NWS anu cocog. Ambang frostbite dinilai dina skala metrik internal supados dua sistem unit satuju.
Temperature apa sing bakal dijupuk kanggo ngukur suhu?
Dina suhu 50 °F (10 °C), atawa nalika anginna kurang ti 3 mph (5 km/h), anginna henteu aya pangaruh anu ngaduruk, sarta suhuna sarua jeung suhu udara, jadi kalkulatorna ngabalikeun angka anu langkung handap dina kaayaan éta.
