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 represents how cold it feels when wind is factored in with the actual air temperature.

2. How Does the Calculator Work?

The calculator uses the standard wind chill formula:

Where:

• \( T \) — Air temperature (°C)
• \( V \) — Wind speed (km/h)

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 assessing risk of frostbite and hypothermia. It helps in making decisions about outdoor activities and appropriate clothing in cold weather.

4. Using the Calculator

Tips: Enter temperature in Celsius and wind speed in km/h. The wind speed must be ≥ 0 km/h for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: At what temperature is wind chill calculated?
A: The formula is valid for temperatures at or below 10°C and wind speeds above 4.8 km/h.

Q2: Does wind chill affect objects?
A: No, wind chill only describes how it feels to humans. Objects will cool to the actual air temperature.

Q3: Why does wind make us feel colder?
A: Wind removes the thin layer of warm air next to our skin, increasing heat loss from the body.

Q4: How accurate is the wind chill formula?
A: It's a standardized model based on human face models and provides a good estimate of perceived temperature.

Q5: Are there different formulas for different countries?
A: Some countries use slightly different formulas, but this is the standard international formula.
