The form dialogue box contains command button like New, Delete, Restore, Find Prev, Find Next, Criteria, and Close. 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. Just input your values and the heat index value will be automatically calculated as you type. =ROUND(16.923+((1.85212*(10^-1))*A2)+(5.37941*B2)-((1.00254*(10^-1))*A2*B2)+. Not me. Of course they say the same thing for every place in the United States, except maybe San Diego and Miami. Humidity %. With everything else blank, that meant Temperature=0 and Humidity=0. For instance, if the temperature is 32°C and 70% relative humidity, the heat index is 41°C. Thanks, Dick. It is not advised to keep any function of Conditional Formatting applied in data for a long time. version of the Heat Index equation: HI = -42.379 + 2.04901523T + 10.14333127R - 0.22475541TR - 6.83783x10 -3 T 2 - 5.481717x10 -2 R 2 + 1.22874x10 -3 T 2 R + 8.5282x10 -4 TR 2 - 1.99x10 -6 T 2 R 2 The humidex factor provides a single number that reflects how the temperature feels based on the actual temperature and the relative humidity. There are several ways of implementing the Trapezoid Rule. Features List:-Calculates current heat index using temperature and relative humidity or temperature and dew point.-Celsius and Fahrenheit both supported. There’s an actual formula that’s used to find the heat index. And if I set Humidity to 50, I got 308…. This computation, too, is done by my TI-83+/84+ program and my Excel workbook below.

Always clear the conditional formatting rule once its use is done. In those cases, a simpler formula is applied to calculate values consistent with Steadman's results: HI = 0.5 * {T + 61.0 + [(T-68.0)*1.2] + (RH*0.094)} In practice, the simple formula is computed first and the result averaged with the temperature. It equals H = T + (0.5555 * (e - 10)), where T is the temperature in Celsius and e is the vapor pressure in millibars (mb). Keep in mind, this heat index chart was devised for shady, light wind conditions, so exposure to full sun can increase values by up to 15°F. It’s important to note that you should use Fahrenheit with this formula, so if you have a temperature in Celsius (or Kelvin), convert it first. Find Next: Finds the next record.
