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.
Zvimwe zvinobvunzwa zvakanyanya
Chii chinonzi chikafu chemusango?
NWS formula (2001) muzviuru zvemaunits ndeye WC = 35.74 + 0.6215T − 35.75V^0.16 + 0.4275T·V^0.16, ne T mu °F uye V mu mph. Inogona kufanotaura kushaya kwemhepo kubva pamuviri wakasviba sezvinoita mhepo inobvisa mavara anopisa anenge pasi pemuviri.
Panguva ipi inoitika kutonhora kwemhepo?
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.
Nzira yakareba sei inogona kuitika frostbite?
Kana mhepo ichibuda pasi pe-18 °C (0 °F) frostbite inowanzova nenjodzi, uye pasi pe-28 °C (-19 °F) muviri unopisa unopisa mu30 min kana kuti zvishoma - zviri nyore mumhepo yakaoma.
Uchi chiller uswa kukonzera zvinhu, kana chete vanhu?
Chill kwemhepo inotarisa kuti sei muviri wakachena unorasikirwa nemhepo, saka inoita kuti vanhu nenyama vaone kuti vane mhepo yakachena, asi haigone kutonhora zvinhu semotokari kana mapfekero emvura pasi pechiyero chemhepo chavanonzwa.
Nei kuwanda kwemhepo kusingaite kuti zvive zvakaomarara?
Formula inoshandisa kukwira kwemhepo kusvika kusimba re0.16, iro rinokwira zvakadzikama pakutanga uye rinova rakapfava. Kubva pa5 kusvika 15 mph kunoderedza tembiricha yakafanana neyekunzwa, asi kubva pa40 kusvika pa50 mph kunochinja zvishoma.
Chirongwa ichi chinoshandawo mu °F/mph uye °C/km/h?
Ndinoda. Choose imperial to enter °F and mph or metric for °C and km/h, and it applies the matching NWS equation. The frostbite thresholds are judged on the metric scale internally so both unit systems agree.
Pazvinenge zvakaita sei kuti mhepo iite kuti chiedza chirege kuitika?
Pamusoro pe50 °F (10 °C), kana kana mhepo ichienda pasi pe3 mph (5 km/h), mhepo ine mhedzisiro yekuchenesa uye tembiricha inoratidzika kunge imwechete neyemhepo tembiricha — saka kalkulatori inodzokera kune imwe nhamba kupfuura kune imwe nhamba pasi pemamiriro aya.
