This calculator helps to calculate the Heat Index and Humidex factor. The heat index, (apparent temperature) is what the temperature feels like to the human body when relative humidity is combined with the air temperature. The humidex (short for humidity index) is an index number used by Canadian meteorologists to describe how hot the weather feels to the average person, by combining the effect of heat and humidity.

How to Use:
