So even though the thermometer reads 39☏, with the wind it feels like 34☏.įor metric units, the wind chill formula isġ3.12 + (0.6215)T - (11.37)V 0.16 + (0.3965)TV 0. It also estimates the exposure time that will cause frostbite. Then the felt temperature isģ5.74 + (0.6215)(39) - (35.75)7 0.16 + (0.4275)(39)7 0.16 This calculator estimates wind chill temperature based on air temperature and wind speed. If the outside temperature is T degrees Fahrenheit and the wind velocity is V miles per hour, then the apparent temperature with wind chill factored in isģ5.74 + (0.6215)T - (35.75)V 0.16 + (0.4275)TV 0.16Įxample: Suppose the current temperature is 39☏ and the wind speed is 7 mph. Choose either US units (degrees Fahrenheit and miles per hour) or metric units (degrees Celsius and Kilometers per hour). Heat Index Calculator - Computes the heat index based on temperature and relative humidity using a formula developed by the. You can also use the convenient wind chill calculator on the left. The formula below will tell you what the outside weather feels like for a given temperature and wind speed. You can find this information on the news or online weather reports. The wind chill temperature is never higher than the air temperature, and the windchill is undefined at higher temperatures (above 10 C). To calculate wind chill, you only need to know the current outside temperature and the speed at which the wind is blowing. We call it wind chill because wind is what primarily makes cold weather feel even more frigid. Let V be the wind speed relative to the object in mph and T be the temperature of the air in Fahrenheit measured by a thermometer, then: This formula works for temperatures below 50 degrees Fahrenheit, and speeds above 3 mph. It does not store any personal data.The wind chill factor, or simply "wind chill," is the phenomenon in which the outside temperature feels colder than what the thermometer reads. To calculate the effective temperature due to windchill, we can use the following formula.

This application note defines the term wind chill, provides equations for estimating it, includes datalogger programming examples, and discusses the limitations. Wind chill numbers are dependably lower than the air temperature for qualities where the equation is. This cookie is set by GDPR Cookie Consent plugin. Wind Chill is the term used to describe the rate of heat loss on the human body resulting from the combined effect of low temperature and wind.

You have the following wind type options: Light air. You can input the wind speed manually, or you can pick the wind type, at which point, the calculator will determine the wind speed. These cookies ensure basic functionalities and security features of the website, anonymously. The wind chill calculator calculates how cold it feels based on the temperature and wind speed. Bright sunshine tends to elevate the apparent temperature. After performing the calculation, make an adjustment for sunshine. Necessary cookies are absolutely essential for the website to function properly. If you use mph and F, the formula is Wind chill temperature 35.74 + 0.6215T 35.75V0.16 + 0.4275TV0.16.
