Quick answer
Wind chill uses the 2001 NWS formula and applies at 50°F or below with winds above 3 mph.
T_wc = 35.74 + 0.6215T − 35.75V^0.16 + 0.4275TV^0.16

Frequently asked questions
Does wind chill affect cars or pipes?
No. Wind chill only describes heat loss from exposed skin — objects cool faster but never below the air temperature.
When does the formula apply?
At 50°F or below with wind above 3 mph; outside that range it isn't meaningful.
