Anyone know how frostbite thresholds are calculated?

[Jack]

I think that bplus has the right idea, as sick as I am of reading about ChatGPT this ChatGPT that, here's what it says about SMcNeill's queastion

Frostbite thresholds are determined based on several factors, including air temperature, wind speed, humidity, and duration of exposure. These factors can affect the rate at which heat is lost from the body, leading to the development of frostbite. The most commonly used method to calculate the frostbite threshold is by using the Wind Chill Index, which takes into account both air temperature and wind speed. Other factors such as clothing and activity level can also impact the threshold. The exact calculation of the frostbite threshold can be complex and may vary depending on the specific conditions.
