Wind Chill Calculator
Estimate how cold it actually feels by combining air temperature with wind speed in mph or km/h—essential for winter running, hiking, or job-site planning.
Factor wind speed into cold air readings to estimate frostbite risks.
Wind chill equation
Wind chill (°F) = 35.74 + 0.6215T − 35.75V^0.16 + 0.4275T·V^0.16 (valid when T ≤ 50°F and V ≥ 3 mph).
Inputs are Fahrenheit (automatically converted from °C if needed) and wind speed in mph (converted from km/h).
How to use
- Enter air temperature in °F or °C.
- Provide wind speed in mph or km/h (must be ≥ 3 mph for the formula to apply).
- Read the feels-like value plus cold-risk guidance such as "frostbite in 30 minutes."
Example
Input: Temperature = 20°F, Wind = 15 mph
Output: Wind chill ≈ 6°F (−14°C) with frostbite risk inside 30 minutes

Deep dive & study plan
The Wind Chill Calculator is a go-to tool whenever you need to calculates wind chill and frostbite guidance from temperature plus wind speed.. It focuses on wind chill, feels like cold, frostbite, which means searchers often arrive with intent-heavy queries like “how to wind chill calculator quickly” or “wind chill calculator formula explained.” Use this calculator to capture those intents and keep learners on the page long enough to send positive engagement signals.
Under the hood, the calculator leans on inputs are fahrenheit (automatically converted from °c if needed) and wind speed in mph (converted from km/h).—that’s why we surface the full expression (“Wind chill (°F) = 35.74 + 0.6215T − 35.75V^0.16 + 0.4275T·V^0.16 (valid when T ≤ 50°F and V ≥ 3 mph).”) directly above the interactive widget. When you embed that formula inside H2s or supporting paragraphs, you help both humans and crawlers understand what entity the page represents.
Execution matters as much as the math. Follow the built-in procedure: Step 1: Enter air temperature in °F or °C. Step 2: Provide wind speed in mph or km/h (must be ≥ 3 mph for the formula to apply). Step 3: Read the feels-like value plus cold-risk guidance such as "frostbite in 30 minutes.". Each numbered instruction is short enough to scan on mobile but descriptive enough to satisfy Google’s Helpful Content guidelines. Encourage students to jot down units, double-check signs, and compare answers with the Example card to build confidence.
The Example section itself is packed with semantic clues: “Temperature = 20°F, Wind = 15 mph” leading to “Wind chill ≈ 6°F (−14°C) with frostbite risk inside 30 minutes.” Pepper similar narratives throughout your copy (and internal links from related guides) so canonical search intents are answered without pogo-sticking back to Google.
Quick retention checklist
- Speak the formula aloud (or annotate it) so the relationships stick.
- Write each step in your own words and compare with the numbered list above.
- Swap in new numbers for the Example to make sure the calculator (and your logic) handles edge cases.
- Link out to at least two related calculators to keep readers exploring your topical hub.
FAQ & notes
Why does the calculator stop changing above 50°F?
The official wind chill formula is only defined for air temperatures up to 50°F (10°C). Above that, convection has little effect so it simply reports the air temperature.
Does humidity factor in?
Wind chill only considers wind speed and air temperature. Use the heat index calculator when humidity drives discomfort instead.
What formula does the Wind Chill Calculator use?
Inputs are Fahrenheit (automatically converted from °C if needed) and wind speed in mph (converted from km/h).
How do I use the Wind Chill Calculator?
Enter air temperature in °F or °C. Provide wind speed in mph or km/h (must be ≥ 3 mph for the formula to apply). Read the feels-like value plus cold-risk guidance such as "frostbite in 30 minutes."
