The NWS Wind Chill Temperature uses advances in science, technology, and computer modeling to provide an accurate, understandable, and useful formula for calculating the dangers from winter winds and freezing temperatures.
Estimate the wind chill temperature based on the air temperature and wind speed using this online calculator. See the wind chill chart for different wind speed units and temperature units.
Enter a temperature and wind speed that you would like calculated: What the temperature feels like to your body: Fahrenheit Celsius. ° F. mph knots m/s k/h. ° C. Watts per Meter Squared. The wind chill calculator only works for temperatures at or below 50 ° F and wind speeds above 3 mph.

In winter, the temperature felt by the body is typically lower than the actual air temperature. This is similar to the body feeling a higher temperature under high humidity conditions in the summer. Refer to the Heat Index Calculatorfor further detail. A surface, such as the skin on a person's body, loses heat through conduction, convection, and ra...
The perception of lower temperatures caused by wind led to the development of many different formulas that attempt to qualitatively predict the effect of wind on this perceived temperature. Because wind chill temperature is not an exact science, weather services in different countries use standards relevant to their particular region, and thus its ...
Frostbite can occur when skin or other tissue is exposed to low temperatures. Usually, the first signs of frostbite involve numbness, discoloration of the skin, and feeling cold, typically in the extremities of the body. More serious complications include hypothermia (which will be discussed below) and compartment syndrome, a condition that results...
Hypothermia occurs when the body dissipates more heat than it absorbs, leading to a reduction of body temperature. In humans, hypothermia is defined as a core temperature below 95.0°F (35.0°C). Symptoms can range from mild shivering to cardiac arrest. Hypothermia most commonly occurs as a result of exposure to extreme cold. It can also occur from o...
Frostbite and hypothermia can both occur as a result of low temperatures, and can lead to serious permanent, and sometimes life-threatening complications. As such, it is important to dress appropriately and understand the risks associated with exposure to low temperatures for extended periods of time. Below is some general advice on how to stay war...
Estimate the temperature felt by the body as a result of wind speed and actual air temperature. Learn about wind chill, frostbite, hypothermia, and how to dress warmly for winter.
It shows air temperature in degrees Fahrenheit and wind speed in miles per hour. Here’s how to convert from Fahrenheit to Celsius. The chart also includes a frostbite indicator, showing the points where temperature, wind speed, and exposure time will produce frostbite in humans.
Wind chill (popularly wind chill factor) is the sensation of cold produced by the wind for a given ambient air temperature on exposed skin as the air motion accelerates the rate of heat transfer from the body to the surrounding atmosphere. Its values are always lower than the air temperature in the range where the formula is valid.
