Heat Index (HI)application calculates heat index from air temperature and relative humidity. Relative humidity is supplied in %.
HI is sometimes referred to as the "apparent Temperature". The HI, given in degrees F, is a measure of how hot it feels when relative humidity (RH) is added to the actual air temperature
Weather for current location including heat index depending on GPS and weather data availability. Temperature is displayed in degrees F and speed is displayed in MPH.
