Others include your age and body type as well as the type of clothes you are wearing, the amount and type of exercise you are engaged in and whether or not your clothes are damp from snow, rain or even perspiration. Windchill is the meteorological index which combines the effects of wind speed and temperature. The technique for measuring windchill was developed in Antarctica during the Second World War. The scientists then developed formulas for relating heat loss to wind speed and air temperature. The coldest windchill in Canada occurred at Pelly Bay in the Northwest Territories.
Watts are energy units.
For example, watts describe the energy requirements of light bulbs. Equivalent temperature is a temperature index which tells you how cold the temperature of the air feels because of the wind. Windchill Chart - Environment Canada has developed a chart that explains what windchill factor means to you in terms of dress and activity. The chart provides a range of windchill values and describes the precautions you should take at each level. Windchill values are easy to understand.
