Frostbite is most likely to affect people who are exposed to low temperatures for long periods of time such as those who participate in winter sports, work jobs that involve being outside in cold temperatures for extended periods of time, and those who are homeless. Exposed skin may freeze in less than two minutes. In the United States, this simple version of the AT is known as the heat index. Wikimedia Commons has media related to Wind chill. This calculator uses the formula developed by the National Weather Service in the United States, which was listed below.
The NWS Wind Chill Temperature (WCT) index uses advances in science, technology, and computer modeling to provide an accurate, understandable, and. This page offers a collection of resources about the new wind chill chart and formula from the National Weather Service.

Wind Chill Calculator. Enter a temperature, in either Fahrenheit or Celsius. Then enter a Wind Speed, in Wind Chill Chart and Explanation · Winter Weather.
How quickly frostbite occurs is dependent on the temperature and level of exposure. 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.
Hypothermia most commonly occurs as a result of exposure to extreme cold. Look up wind chill in Wiktionary, the free dictionary. This article is about the meteorological effect of "wind chill". Archived from the original on 11 October

Video: Wind chill to temperature chart What is the current wind chill temperature?
Hypothermia occurs when the body dissipates more heat than it absorbs, leading to a reduction of body temperature. In the s, wind chill began to be reported as a wind chill equivalent temperature WCETwhich is theoretically less useful. Retrieved 14 January Wind chill numbers are always lower than the air temperature for values where the formula is valid.
A surface, such as the skin on a person's body, loses heat through conduction, convection, and radiation.

The formula used in the U.S. and Canada to express the combined effect of wind and low temperature on how cold it feels was changed in. Use this Wind Chill Calculator to determine the wind chill temperature based on Estimated Wind Chill Temperature:, Wind Chill Chart.
In the United States, this simple version of the AT is known as the heat index. Human Factors Design Handbookpage The apparent temperature ATinvented in the late s, was designed to measure thermal sensation in indoor conditions.
Frostbite has historically been described in terms of degrees of frostbite, similar to that of burns:. In winter, the temperature felt by the body is typically lower than the actual air temperature. Frostbite can be prevented by taking certain precautions when circumstances put a person in a situation that involves low temperatures.
Wind Chill Calculator
The windchill equivalent temperature is simply a way or relating how wind appears to make a given temperature cool things as though it were really much colder.

August, Press Release:". Although conduction and radiation are relevant to heat transfer, wind chill temperature is mostly a result of convection.
In the s, wind chill began to be reported as a wind chill equivalent temperature WCETwhich is theoretically less useful.

The equivalent formula in US customary units is: . It can also occur from other conditions such as alcohol intoxication, low blood sugar, anorexia, and advanced age. Convection is defined as heat transfer due to the bulk movement of molecules within fluids such as gases and liquids, such as wind.
Limit outdoor activities to short periods of time or, ideally, cancel outdoor activities entirely. As the air temperature falls, the chilling effect of any wind that is present increases. These include:.
