The Template:Heat_index calculates the heat index, for a specified temperature and relative humidity (parameters 1 & 2), using a formula from the U.S. National Weather Service (NWS). [ 1 ] Science
A generalized view of the heat index showing how the perception of heat by the human body increases with temperature but more rapidly at higher humidity levels. The heat index of a given combination of temperature and humidity is defined as the dry-bulb temperature which would feel the same if the water vapor pressure were 1.6 kPa. Quoting ...
