What is wind chill?
Wind chill describes how cold the air feels on exposed skin when wind is factored in. Moving air removes heat from the body faster.
When is the formula valid?
The NWS wind chill formula is valid for temperatures at or below 10°C (50°F) and wind speeds above 4.8 km/h (3 mph).
Is it free?
Yes, all calculators are completely free.
