Overview
Wind chill is the lowering of body temperature due to the passing-flow of lower-temperature air. Wind chill numbers are always lower than the air temperature for values where the formula is valid.
💡
Pro Tips
The formula is valid for temperatures at or below 10°C (50°F).
Wind speeds must be above 4.8 km/h (3 mph) for a significant effect.
Wind chill only describes the effect on skin, not on inanimate objects.

Fun Facts
"Your body creates a thin 'boundary layer' of warm air around your skin; wind strips this layer away."
"In extremely cold wind chills, frostbite can occur on exposed skin in less than 30 minutes."
"The modern North American wind chill index was implemented in 2001."
