The Heat Index
“How can we measure how a temperature really feels?”
We all know how to read a normal thermometer. However, when it gets really humid, then oftentimes it will feel much hotter than it really is. So how can we use our scientific mindset to quantify this phenomenon? Well, what if we were to create a formula that combines both the absolute temperature and the relative humidity to produce a value? Well, this is the idea behind the heat index and is used by weather forecasters and HVAC systems analysts all over the world.
