How do you calculate the wind chill factor?
A good approximation of the wind-chill temperature can be found by multiplying the wind speed by 0.7 and then subtracting that value from the air temperature.
What is meant by the windchill factor?
The windchill factor is the temperature that a person feels because of the wind. For example, if a thermometer reads 35 degrees Fahrenheit outside and the wind is blowing at 25 miles per hour (mph), the windchill factor causes it to feel like it is 8 degrees F.
How long does it take to get frostbite at 28 degrees?
The colder it gets, the faster you get frostbite. And when you add wind and water, the process speeds up even more. Every person and every situation is different, but here are a few guidelines to know: Once sub-zero temps hit, it takes about 30 minutes for exposed skin to get frostbite.
Is 5mph windy?
Breezy is described as a sustained wind speed from 15-25 mph. Windy is a sustained wind speed from 20-30 mph.

Can you get frostbite in 30 degree weather?
Below 32 degrees, wind can cause you to get frostbite faster. Above 32 degrees, you cannot get frostbite, but you can get hypothermia, which occurs when your body temperature falls below 95 degrees.
What is the new wind chill temperature index?
The new Wind Chill Temperature Index, by Randall Osczevski of DCIEM and Maurice Bluestein of Purdue University in Indiana, makes use of advances in science, technology and computer modelling to provide a more accurate, understandable and useful formula for estimating the dangers arising from winter winds and freezing temperatures.
What is the wind chill?
Note that the Wind Chill is only defined for temperatures in the range -45oF to +45oF and wind speeds 3 to 60 mph. Note also that water will not freeze unless its temperature (not the wind chill temperature) reaches the freezing point. Wind Chill FAQs
What is the threshold for frostbite from wind chill?
Frostbite Threshold: For the first time, the wind chill temperatures include specific threshold values that provide specific warning of time-to-frostbite at given levels of wind chill. For example, a temperature of 5 degrees Fahrenheit and a wind speed of 30 mph equal a wind chill of -19, which will produce frostbite in 30 minutes.
