There actually is a sound formula to it, because heat loss increases with the wind speed. A wind chill of -15 means that your body loses heat at the same rate it would in calm air at -15.

There is an online wind chill calculator here.

BTW in Winnipeg they express the wind chill in minutes- as in the amount of time it takes for frostbite to set in.

Thanks for the information, Squawk. Now I know it’s not just a made-up forecast to hype weather reports.
