25 Αυγ 2023 · Choose the appropriate calculator and enter the values. Then click "Calculate". * Please note: The Heat Index calculation may produce meaningless results for temperatures and dew points outside of the range depicted on the Heat Index Chart linked below.
Calculate the heat index based on air temperature and relative humidity using this online tool. See the heat index formula, chart and examples for different temperature units.
The heat index (HI) is an index that combines air temperature and relative humidity, in shaded areas, to posit a human-perceived equivalent temperature, as how hot it would feel if the humidity were some other value in the shade. For example, when the temperature is 32 °C (90 °F) with 70% relative humidity, the heat index is 41 °C (106 °F ...
12 Μαΐ 2022 · The computation of the heat index is a refinement of a result obtained by multiple regression analysis carried out by Lans P. Rothfusz and described in a 1990 National Weather Service (NWS) Technical Attachment (SR 90-23).
Heat Index. by Tim Brice and Todd Hall. Enter a temperature that you would like and choose your units: What the temperature feels like to your body: Fahrenheit Celsius. ° F. Enter your relative humidity: %.
Learn how to compute the heat index, an apparent temperature that reflects the combined effect of temperature and humidity, using a regression equation and adjustments. The web page also explains how to estimate the forecast daily mean heat index based on the maximum and minimum values.
