Aangaande hierdie sakrekenaar
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.
Dikwels gevra vrae
Wat is die windkoudformule?
The NWS formula (2001) in imperial units is WC = 35.74 + 0.6215T − 35.75V^0.16 + 0.4275T·V^0.16, with T in °F and V in mph. It models heat loss from bare skin as wind strips away the thin warm layer around the body.
Wanneer is windkoue van toepassing?
Dit word gedefinieer vir temperature teen of onder 50 °F (10 °C) en winde bo ongeveer 3 mph (5 km/h).'n Wind het bo - op daardie een min verkoelende uitwerking en die "gevoelens soos" is gelyk aan die lugtemperatuur.
Hoe vinnig kan rypbiet plaasvind?
When the wind chill drops below roughly −18 °C (0 °F) frostbite becomes a risk, and below about −28 °C (−19 °F) exposed skin can freeze in 30 minutes or less — sooner in more extreme wind chills.
Het windkoue'n uitwerking op voorwerpe, of net mense?
Net lewende, warmer-ean-lug dinge. Wind koue maatreëls hoe vinnige 'n warm liggaam hitte verloor, so dit laat mense en diere kouer voel, maar dit kan nie 'n voorwerp soos' n motor of 'n water pyp onder die werklike lugtemperatuur afkoel nie.
Waarom hou meer wind nie aan om dit na verhouding kouer te laat voel nie?
The formula uses wind speed to the power 0.16, which rises steeply at first and then flattens. Going from 5 to 15 mph drops the feels-like temperature a lot, but going from 40 to 50 mph changes it only slightly.
Werk die sakrekenaar in albei °F/mph en °C/km/h?
Ja. Kies die keiser wat die gradef en mf of metrieke vir °C en km/h moet invoer, en dit pas die vergelyking van NWS toe. Die rypbiet se drumpels word geoordeel op die metrieke skaal wat inwiese mate is sodat albei eenhede saamstem.
Teen watter temperatuur hou windkoud op om te saak?
Above 50 °F (10 °C), or when the wind is below about 3 mph (5 km/h), wind has little cooling effect and the feels-like temperature equals the air temperature — so the calculator returns a note rather than a lower number in those conditions.
