To calculate heat index, it is HI=C^1+C^2T+C^3R+C^4TR+C^5T^2+C^6R^2+C^7T^2R+C^8TR^2+C^9T^2R^2 ^=power number , T=ambient dry-bulb temperature, R=relative humidity. 2 Answers. When the heat index is very high, people may be at increased risk for heat exhaustion and heat stroke. Both the wind chill and heat index feels like temperatures are calculated using several complicated mathematical formulas. Sharp discontinuity there. Alternatively, on breezy days, the increased wind speed can make it feel cooler outside than it really is. How does that work? When the weather forecast says something like “it will be 32°C today, but with all this humidity it will feel like it is 40°C” what does that mean? How to use this calculator.
