This calculator estimates heat index temperature felt by the human body based on the actual measured air temperature together with humidity level or dew point.
Heat Index. The Heat Index is a measure of how hot it really feels when relative humidity is factored in with the actual air temperature. To find the Heat Index temperature, look at the Heat Index Chart above or check our Heat Index Calculator.
The ‘Heat Index’ is a measure of how hot weather "feels" to the body. This table uses relative humidity and air temperature to produce the "apparent temperature" or the temperature the body "feels".
21 Ιουλ 2016 · Calculate the heat index from the temperature and humidity (either relative humidity or dew point), or use a simple heat-index conversion chart.
18 Απρ 2024 · Use this heat index chart to understand how relative humidity affects perceived temperature and can increase the risk of heat stress.
