풍냉 공식

Wind Chill (°F) = 35.74 + 0.6215×T - 35.75×V^0.16 + 0.4275×T×V^0.16

여기서 T = 온도(°F), V = 풍속(mph)입니다.

풍냉 공식은 50°F 이하의 온도, 3 mph 이상의 풍속에서 유효합니다.

How to Use

1
Select your unit system — Imperial (°F, mph) or Metric (°C, km/h)
2
Enter the current air temperature — wind chill is only valid for temperatures at or below 50°F (10°C)
3
Enter the wind speed — must be above 3 mph (4.8 km/h) for the formula to apply
4
View your wind chill temperature, danger level, and estimated frostbite time
5
Use the quick calculate buttons for common temperature and wind speed scenarios
6
Understanding the key inputs — wind chill measures how cold it feels when wind is factored in, not the actual air temperature. The faster the wind, the faster your body loses heat through convection
7
Interpreting the results — the frostbite time shows how quickly exposed skin can freeze at the calculated wind chill. The danger level color coding helps you quickly assess outdoor safety
8
Check the wind chill chart below for a comprehensive overview of wind chill values across a range of temperatures and wind speeds to plan outdoor activities safely

예시

좋은 예시

Winter morning with moderate wind

30°F air temperature with 20 mph wind → wind chill of 17°F — dress warmly in layers and cover exposed skin

Severe cold snap with strong wind

-10°F with 40 mph wind → wind chill of -43°F — frostbite possible in under 5 minutes. Avoid outdoor activity

Mild winter day planning a run

35°F with 10 mph wind → wind chill of 28°F — safe for outdoor exercise with appropriate cold weather gear

Metric unit calculation for European users

0°C with 30 km/h wind → wind chill of approximately -9°C (16°F) — moderate frostbite risk for exposed skin

Comparing conditions for outdoor workers

Monday: 20°F with 15 mph wind (WC 9°F). Tuesday: 10°F with 35 mph wind (WC -11°F). Tuesday is significantly more dangerous despite only 10°F difference in air temperature

Planning ski trip conditions

Summit: 5°F with 25 mph wind → wind chill of -19°F — frostbite risk in 10-30 minutes. Full face covering and hand protection essential

나쁜 예시

Using wind chill for warm temperatures

Wind chill formula is not valid above 50°F (10°C) — at warm temperatures, wind actually helps cool the body rather than making it feel colder

Ignoring wind chill and only looking at air temperature

A 20°F day with 30 mph wind feels like 3°F — dressing for 20°F alone puts you at risk of frostbite

Confusing wind chill with actual temperature

A wind chill of -30°F does not mean water freezes faster or your car engine behaves differently — it only affects how quickly living tissue loses heat

흔한 실수

Using wind chill above 50°F (10°C) — the formula only applies at cold temperatures where wind accelerates heat loss from exposed skin
Confusing wind chill temperature with actual air temperature — wind chill is a "feels like" measure, not a thermometer reading
Ignoring wind chill when planning outdoor activities — air temperature alone does not reflect the true danger of cold weather exposure
Not covering exposed skin — frostbite can occur in minutes at extreme wind chill values even when the air temperature seems manageable
Assuming wind chill affects objects — wind chill only applies to living tissue and how quickly it loses heat; it does not affect inanimate objects like car engines or pipes
Forgetting that wind chill can be deceptive indoors — looking outside and seeing sunshine can make you underestimate the danger when wind chill is extreme
Not accounting for wind chill when dressing children or elderly — vulnerable populations lose heat faster and are more susceptible to cold injury
Using wind speed at ground level when the reported wind is measured at a different height — official wind measurements are typically taken at 33 feet (10 meters) above ground

자주 묻는 질문

What is the wind chill formula?

The National Weather Service wind chill formula is: $\text{Wind Chill} = 35.74 + 0.6215 \times T - 35.75 \times V^{0.16} + 0.4275 \times T \times V^{0.16}$ , where $T$ is the air temperature in °F and $V$ is the wind speed in mph. This formula was adopted in 2001 based on research from the University of Toronto.

At what wind chill temperature does frostbite occur?

Frostbite risk increases as wind chill drops. At wind chills between -4°F and 13°F (-20°C to -10°C), frostbite can occur in about 30 minutes. At -18°F to -4°F, frostbite can develop in 10-30 minutes. Below -28°F, frostbite can occur in as little as 5-10 minutes, and below -45°F, exposed skin can freeze in under 2 minutes.

Does wind chill affect cars and water pipes?

No. Wind chill only applies to living tissue and describes how quickly exposed skin loses heat. Inanimate objects like car engines, water pipes, and water freezing points are affected by the actual air temperature, not the wind chill temperature.

What is the difference between wind chill and heat index?

Wind chill measures how cold it feels in winter when wind accelerates heat loss from exposed skin. Heat index measures how hot it feels in summer when humidity slows the body's ability to cool itself through sweating. Both provide a "feels like" temperature that is more useful than the actual air temperature for assessing comfort and safety.

How do I convert wind chill between Fahrenheit and Celsius?

After calculating wind chill in °F using the NWS formula, convert to °C using the standard formula: $°C = (°F - 32) \times \frac{5}{9}$ . Note that you cannot simply convert the input temperature to Celsius and use a different formula — the NWS formula is defined in Fahrenheit, so calculate in °F first and then convert the result.

How accurate is the wind chill calculator?

The calculator uses the exact NWS wind chill formula adopted in 2001, so it is mathematically precise. However, wind chill is an estimate of perceived temperature — individual factors like clothing, activity level, body fat percentage, age, and health conditions affect how cold you actually feel. The calculator provides a standardized reference for planning outdoor activities.

What is the lowest survivable wind chill?

There is no specific wind chill that is immediately fatal, as survival depends on clothing, exposure time, and individual health. However, at wind chills below -50°F (-45°C), unprotected exposed skin can freeze in under 5 minutes, and hypothermia becomes a serious risk within 10-15 minutes even with winter clothing. At -75°F (-60°C) and below, outdoor conditions are considered hazardous and all outdoor activities should be canceled.

At what temperature should I worry about wind chill?

Wind chill becomes a concern when the air temperature drops below 40°F (4°C) and wind speeds exceed 10 mph. At this point, exposed skin starts losing heat faster than it can be replaced. The NWS issues wind chill advisories when wind chill is expected to reach -15°F (-26°C) or lower, and wind chill warnings at -25°F (-32°C) or lower.
