Wind Chill Calculator
Wind Chill Calculator Online – Calculate Wind Chill Easily
Intro
A Wind Chill Calculator online is a practical tool that helps you find out how cold it actually feels when wind is factored in with air temperature. While a thermometer shows the actual air temperature, wind chill measures the cooling effect of wind on exposed skin, giving the “feels-like” temperature.
This tool is especially useful for people living in colder regions, outdoor workers, athletes, hikers, and travelers. Knowing the wind chill can help you dress properly, plan outdoor activities safely, and protect yourself from frostbite and hypothermia.
Formula / Working
The Wind Chill (WC) is calculated using a standard formula developed by the U.S. National Weather Service: WC=35.74+0.6215T−35.75V0.16+0.4275TV0.16WC = 35.74 + 0.6215T – 35.75V^{0.16} + 0.4275T V^{0.16}WC=35.74+0.6215T−35.75V0.16+0.4275TV0.16
Where:
- WC = Wind Chill (°F)
- T = Air Temperature (°F)
- V = Wind Speed (mph)
⚠️ Note: This formula applies when temperature is 50°F (10°C) or lower and wind speed is 3 mph or higher.
The calculator applies this formula automatically, giving you the feels-like temperature instantly.
Step-by-Step Usage
Here’s how you can use the Wind Chill Calculator online:
- Enter the air temperature (°C or °F).
- Enter the wind speed (mph or km/h).
- Click “Calculate.”
- Instantly see the wind chill (feels-like temperature).
Examples
Example 1: Cold Breezy Day
- Temperature = 30°F (-1°C)
- Wind Speed = 10 mph
WC=35.74+(0.6215×30)−(35.75×100.16)+(0.4275×30×100.16)≈21°FWC = 35.74 + (0.6215 \times 30) – (35.75 \times 10^{0.16}) + (0.4275 \times 30 \times 10^{0.16}) \approx 21°FWC=35.74+(0.6215×30)−(35.75×100.16)+(0.4275×30×100.16)≈21°F
Result: It feels like 21°F (-6°C), colder than the actual temperature.
Example 2: Strong Wind in Freezing Weather
- Temperature = 20°F (-7°C)
- Wind Speed = 25 mph
Result: Wind chill is about 3°F (-16°C), which can be dangerous with prolonged exposure.
Example 3: Mild Cold but High Winds
- Temperature = 40°F (4°C)
- Wind Speed = 20 mph
Result: Wind chill is about 30°F (-1°C), making it feel much colder than the thermometer reading.
