The Heat Index Calculator is a useful tool that combines air temperature and relative humidity to determine the human-perceived equivalent temperature. By inputting the air temperature and dew point temperature or relative humidity, this calculator swiftly provides the heat index or apparent temperature. It aids in making informed decisions for outdoor activities and monitoring potential heat-related health risks, especially during extreme heat events.

This user-friendly calculator offers the flexibility to choose temperature units, provides a quick conversion tool, and displays the heat index temperature in various units. Additionally, it includes a "Thermometer" screen that showcases temperature, wind speed, wind direction, dew point temperature, humidity, and Air Quality Index of your current location. The forecast feature predicts the heat index for the next 3 hours, enhancing preparedness for changing weather conditions.
