1. What is Wind Chill?

Wind chill is the perceived decrease in air temperature felt by the body on exposed skin due to the flow of air. It estimates how cold it feels when wind is factored in with the actual air temperature.

2. How Does the Calculator Work?

The calculator uses the National Weather Service wind chill formula:

Where:

• \( T \) — Air temperature (°F)
• \( V \) — Wind speed (mph)

Explanation: The formula calculates how wind speed affects the perception of temperature on exposed human skin.

3. Importance of Wind Chill Calculation

Details: Wind chill is important for understanding the risk of frostbite and hypothermia during cold weather. It helps in making appropriate clothing choices and weather warnings.

4. Using the Calculator

Tips: Enter temperature in Fahrenheit and wind speed in miles per hour. Wind speed must be ≥ 0 mph. The formula is valid for temperatures ≤ 50°F and wind speeds ≥ 3 mph.

5. Frequently Asked Questions (FAQ)

Q1: Why does wind make it feel colder?
A: Wind removes the thin layer of warm air next to your skin, increasing heat loss from your body.

Q2: Does wind chill affect objects?
A: No, wind chill only affects living things. Objects will cool to the actual air temperature.

Q3: What's the difference between old and new wind chill formulas?
A: The current formula (implemented in 2001) is based on human face models and provides more accurate results.

Q4: At what wind speed does wind chill become significant?
A: Wind chill becomes noticeable at about 5 mph and increases with higher wind speeds.

Q5: How does humidity affect wind chill?
A: The current formula doesn't account for humidity, but in reality, moist air can make cold feel more intense.
