A heat index and wind chill calculator determines the perceived temperature ("feels like") based on actual temperature, humidity (heat index above 27°C) or wind speed (wind chill below 10°C). High humidity makes hot temperatures feel hotter because sweat evaporation slows; strong winds make cold temperatures feel colder by removing the insulating air layer.

Guía paso a paso

  1. 1Input air temperature and wind speed
  2. 2Calculate wind chill factor
  3. 3Determine apparent temperature
