to measure how hot it feels when relative humidity (RH) is added to the actual air temperature. Heat Index Calculator
Formula Used: Heat Index = -42.379 + (2.04901523 x T) + (10.14333127 x R) - (0.22475541 x T x R) - (6.83783x10-3 x T2) - (5.481717x10-2 x R2) + (1.22874x10-3 x T2 x R) + (8.5282x10-4 x T x R2) - (1.99x10-6 x T2 x R2) Where, T = Temperature in °F R = Relative Humidity in % Heat index is utilized only in warm weather Hence accepted value will be >=70° F This online Thermal calculator helps you dynamically to calculate the Heat Index easily. | |||||||||||
