My father doesn't believe in wind-chill factor because they didn't have it in his day.

A mix of air temperature, relative humidity and wind speed is what causes the difference in temperature perception. Wind chill temperature is not an exact science. Weather services in different countries make many assumptions that may differ from those provided by local weather services in other countries. Have you eaten fish?

The wind chill was 13.12 with a 0.6215T.

T is the temperature in degrees Celsius.

V is the wind speed in kilometres per hour.

It can be measured in brass monkeys. It is four today.

Take the wind speed and divide it by 0.7. Then subtract the temperature from that value. The first day of summer in Bodalla, New South Wales, has a wind speed of 7 km and an air temperature of 25C. Not at all. Ursula Nixon is from Bodalla. New South Wales, Australia.

Wind chill lowers the temperature. It doesn't. The temperature can never fall below the still-air reading. The wind speeds up the rate at which exposed skin falls. A strong wind at 0C produces a net rate of body heat loss equivalent to that on a calm day.

Wind chill doesn't affect you if you keep your skin covered. I climbed a Scottish mountain in sideways rain and 45-50mph winds in two base layers and a thin mid layer, plus a waterproof top, because of this. I didn't notice that the temperature was 5C. Even when resting at the summit. Rickytip.

If your nuts and bolts are cold, that's a problem. There is a cat called MysticKitty.

If it is cold enough to freeze the rowlocks, it is cold.

It is the same answer every time.

It is 3C and with the wind-chill factor it is freezing.

It will be -1C tomorrow, and with the wind-chill factor it will be freezing.

And so on.

I would think that the wind-chill effect is dependent on the individual body's ability to warm up. The only way to do this is by the circulation of warm blood in the affected area. Someone with an exposed area that is prone to arthritis will experience wind chill more than someone without any health compromises. It's about core body heat being "chilled" and the difficulties with restoring protection. It is possible to protect surface chilling. The problem is when it becomes difficult to resolve. NewMe358

I was surprised to learn that air temperature is not the only thing that affects how warm a room is. Cold walls or ceilings can increase the loss of heat in the body, even if a thermostat holds the air temperature steady. The indoor air temperature can sometimes be adjusted to compensate for the effect of the outdoor temperatures. A filter reader.

There is an explanation for how to calculate wind chill.

The wind chill factor was designed for a limited purpose. It measures heat loss from exposed areas of the human body in low temperatures and measured wind speeds. With this information, people venturing outside in the bitter weather would know an approximate time before the exposed areas of their body would start to lose their ability to breathe. Biji Dog.

I remember to wear a hooded coat, a woolly scarf, and proper gloves or mittens when the wind chill is making the temperature considerably colder outside, even though I am not good at figures. I also have a beard that helps to prevent frostbite. Richard is from Westmount, Quebec.
