HEAT

Calculates the heat index and relative humidity.

Format

HEAT temp dewpt units

Parameters

temp

temperature for calculating the heat index

dewpt

dew point temperature for calculating the heat index; must be less than or equal to the value in temp

units

units of the specified temperature, dew point and output

 

F

Fahrenheit (default)

 

C

Celsius

 

K

Kelvin

Remarks

The heat index is calculated using an empirical algorithm developed by NOAA.

Valid temperature ranges are 80-110°F, 26.6-43.3°C, or 299.8-316.5°K.

The valid dew point temperature range is 55-85°F, 12.7-29.4°C, or 285.9-302.6°K.

Examples

HEAT 97 72

This entry lists the heat index and relative humidity for a temperature of 97° F and a dew point temperature of 72° F.

HEAT 38 29 C

This entry lists the heat index and relative humidity for a temperature of 38° C and a dew point temperature of 29° C.
