Our calculators are 100% free with no registration, subscriptions, or paywalls required. You can toggle between imperial and metric units, customize input parameters, export calculation summaries, or embed this calculator directly into your own website or blog.
How to Use the Wind Chill Calculator
- 1 Enter the actual air temperature in °F or °C (valid for temperatures ≤ 50°F / 10°C).
- 2 Enter the wind speed in mph, km/h, m/s, or knots (valid for speeds ≥ 3 mph).
- 3 Click the green "Calculate Wind Chill ▶️" button to view the feels-like temperature and frostbite hazard exposure threshold.
Wind Chill Calculator — Frequently Asked Questions
Q1 What is the National Weather Service (NWS) wind chill formula? ▾
Wind Chill (°F) = 35.74 + 0.6215T - 35.75(V^0.16) + 0.4275T(V^0.16), where T is air temperature in °F and V is wind speed in mph.
Q2 At what wind chill temperature does frostbite become a severe danger? ▾
At wind chills below -18°F (-28°C), frostbite can occur on exposed skin within 30 minutes. At -35°F (-37°C), frostbite can occur in 10 minutes.
Q3 Does wind chill affect non-living objects like cars and pipes? ▾
Wind chill only accelerates the rate of cooling down to the ambient air temperature; it cannot cool an object lower than the actual thermometer temperature.
Q4 Why is wind chill only calculated at temperatures at or below 50°F (10°C)? ▾
At warm temperatures above 50°F (10°C), wind facilitates comfortable cooling rather than dangerous cold exposure. Warm weather apparent temperature is measured using the Heat Index.
