Solving for heat index.
heat index equation using ambient dry bulb temperature and relative humidity
c1=
-42.379
c2=
-2.04901523
c3=
-10.14333127
c4=
-0.22475541
c5=
-6.83783 x 10-3
c6=
-5.481717 x 10-2
c7=
-1.22874 x 10-3
c8=
8.5282 x 10-4
c9=
-1.99 x 10-6
The equation requires the temperature to be greater than 80 degrees Fahrenheit and the relative humidify to be above 40 percent. The equation approximates the heat index to within plus or minus 1.3 degrees Fahrenheit.

Inputs:

dry bulb temperature (T)
relative humidity (R)


Conversions:

dry bulb temperature (T)
= 0
= 0
fahrenheit
relative humidity (R)
= 0
= 0
percent

Solution:

heat index (HI)
= NOT CALCULATED
