Heat Index Calculator

How does the Heat Index Calculator work?

Given a temperature in Fahrenheit and a relative humidity percentage, this calculates the Heat Index.
This calculator has 2 inputs.

What 1 formula is used for the Heat Index Calculator?

HI = -42.379 + 2.04901523T + 10.14333127R - 0.22475541TR - 0.00683783T² - 0.05481717R² + 1.22874T²R + 0.00085282TR² - 0.00000199T2R²

What 4 concepts are covered in the Heat Index Calculator?

fahrenheit: Unit of temperature
heat: energy that is transferred from one body to another as the result of a difference in temperature
heat index: measure of how hot it really feels when relative humidity is factored in with the actual air temperature
temperature: degree of hotness or coldness measured on a definite scale. An average measure of the kinetic energy for particles of matter.

Example calculations for the Heat Index Calculator

93% relative humidity and 85 temperature calculate heat index
