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.
heat index °f (°c) The heat index is an accurate measure of how hot it really feels when the affects of humidity are added to high temperature. RELATIVE HUMIDITY (%)
Heat index chart. In order to determine the heat index using the chart above, you need to know the air temperature and the relative humidity. For example, if the air temperature is 100 ° F and the relative humidity is 55%, the heat index will be 124 ° F.
Interactive map of apparent temperature, also known as 'feels like' temperature or 'heat index'.
We use this table to provide you with Heat Index values. These values are for shady locations only. Exposure to full sunshine can increase heat index values by up to 15°F (8°C). Also, strong winds, particularly with very hot, dry air, can be extremely hazardous as the wind adds heat to the body.
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".
16 Ιουλ 2019 · At a Glance. The heat index is how hot it really feels when the relative humidity is factored in with the actual air temperature. When the heat index reaches 100 degrees or higher, it can...
