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.

Wind Chill Calculator Guide
Use this companion guide beside the interactive calculator to make sure you understand the “why” behind every click. Each section includes the classroom explanation, student-friendly language, and quick practice prompts.
Before you start
Collect the data points listed below and double-check their units. Keeping an organized “givens” list is one of the fastest ways to reduce math errors and impress exam graders.
- wind chill
- feels like cold
- frostbite
Detailed 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."
Teaching & troubleshooting tips
Does humidity factor in?
Wind chill only considers wind speed and air temperature. Use the heat index calculator when humidity drives discomfort instead.
