Why wind makes cold colder

Still air insulates; wind strips the warm boundary layer off your skin, accelerating heat loss. The NWS formula models that convective loss on a human face — 20°F with 15 mph wind removes heat like 6°F still air.

It's about skin, not pipes

Wind chill predicts frostbite and hypothermia risk for people and animals — it can't cool objects below the actual air temperature, so pipes and car engines only care about the thermometer. Dress for the feels-like; plumb for the actual.
