![]() However, with a wind chill effect, the possibility of frostbite is greatly increased. If the body overheats to 105.1☏ or more, it is at risk for heat illnesses, such as heat stroke. At these apparent temperatures, the skin essentially cant breathe. Great care should be taken to avoid conditions conducive to low temperatures, with or without wind chill factors. When the heat index is expected to exceed 105-110☏ for 2 or more consecutive days, the NOAA National Weather Service will issue excessive heat alerts for an area. That wind effect tends to evaporate the moisture from the air and cause the enhanced cooling effect to humans, plants and animals, just as a breeze does on a hot summer day. While the change in the wind chill factor above 50 MPH statute is not really negligible, it is minimal. The greatest range of wind speeds for effect is from 5 to 50 MPH statute. There is no effect on either the old or new formula if wind speeds are under 3 MPH statute, while there is no effect on the old system until the are near 5 MPH statute, or the equivalent in other speed designations. Please also visit our temperature conversion programs. You can also see our wind chill table if you prefer. To determine the wind chill temperature, find the value closest to your outside air temperature. For example, riding at 70 mph on the motorway when its 0☌ will feel like -11☌. Change the speed value (in any designation) and watch the effect. Riding your motorbike on a quiet day (with no wind) will feel 4☌ to 12☌ colder, depending on the temperature and your speed. Our default values of 32 degrees Fahrenheit and 1 MPH (nautical) do NOT demonstrate the severe effect of how the air feels based on the wind chill factor. We calculate and display both and as you will see, the new formula has a more intense and chilling result. There are two formulae for calculating the wind chill effect one called the old formula and one called the (obviously) new formula. Click on the calculate button for the wind chill corrected temperature effect, displayed in degrees Fahrenheit and Celsius. You may make either temperature designation entry with any speed designation entry if you wish. Because the user might need the Wind Chill in Watts per meter squared m2, it can (W) be calculated using an air temperature in degrees Celsius (☌) and a wind speed in. Keep in mind that wind speeds of under 5 MPH have a negligible effect on the wind chill calculation. To calculate the wind chill, you need: The temperature: use a thermometer or your current conditions. Then, the Wind Chill can be calculated using this formula: WindChill 35.74 + (0.6215 × T) (35.75 × Wind0.16) sfc + (0.4275 × T × Wind0.16) sfc. To calculate wind chill, enter the current ambient temperature in degrees Fahrenheit (☏) and enter the speed of the wind in miles per hour if you don't know those values in ☏ or MPH (statute miles per hour), enter them in ☌ and knots (often called nautical miles per hour), or KmPH (kilometers per hour) in the appropriate fields. That effect is called the wind chill factor. Often cold temperatures can feel much colder based on the speed of the wind. This calculator requires the use of Javascript enabled and capable browsers.
