Wind chill describes how cold the air feels on exposed skin once you factor in the wind, which strips away the thin layer of warmth your body builds up and speeds heat loss. This calculator uses the 2001 wind chill formula adopted jointly by the United States National Weather Service and Environment Canada, the current standard that replaced older, harsher tables. Enter the air temperature and the wind speed, choose Fahrenheit with miles per hour or Celsius with kilometers per hour, and read the wind chill temperature along with a frostbite risk note. Wind chill only applies at temperatures at or below 50 degrees Fahrenheit and wind above about 3 miles per hour, and the calculator flags when your inputs fall outside that valid range.
