Là gì Wind Chill Calculator?

▾

Wind chill is the perceived decrease in temperature felt by exposed skin due to airflow. Wind increases the rate of heat loss by continuously replacing the layer of warm air near the skin with cooler ambient air. The Environment Canada / NWS formula (2001) uses wind speed and air temperature to calculate the apparent feels-like temperature. It applies when the actual temperature is ≤ 10°C and wind speed > 4.8 km/h.

Calkulon makes complex calculations simple — built for students and everyday problem-solvers.

1Metric (°C, km/h): WC = 13.12 + 0.6215T − 11.37V^0.16 + 0.3965T×V^0.16
2Imperial (°F, mph): WC = 35.74 + 0.6215T − 35.75V^0.16 + 0.4275T×V^0.16
3V^0.16 is the key term — wind speed has diminishing returns
4Developed by Environment Canada and the US NWS in 2001
5Not applicable above 10°C/50°F — no cooling effect from wind when air is warm

Ví dụ có lời giải

▾

Ví dụ 1

Cho trước:−5°C air, 30 km/h wind

Kết quả:Wind chill ≈ −14°C

Exposed skin can freeze in 30 minutes

Ví dụ 2

Cho trước:0°C air, 20 km/h wind

Kết quả:Wind chill ≈ −5°C
