The Fahrenheit scale has only one point of reference for people and that is not 100.

Fahrenheit (the scientist) determined 0° at the coldest stable temperature he could achieve with a mixture of water, ice and ammonium chloride, then set the mean healthy body temperature (as it was known at that time, modern measuring equipment is more precise) at 96° and then as a third reference set 32° as the freezing point of water.
The reference points were later changed to 32° for water freezing and 180° higher at 212° for water boiling due to Anders Celsius work and influence.

Everything about this looks just random and devoid of any logic. Celsius for his scale referenced the temperatures at which water changes state and Kelvin uses the Celsius scale but sets 0 at the point of literally no energy. Behind both is an idea easily to grasp.

They're talking about using Fahrenheit in a day to day capacity like for the weather, not as a scientifically rigorous definition. 0°F is very cold and 100°F is very hot. If you treat it as almost a percentage of how "very hot" it is then it can be a pretty good indicator.

Don't get me wrong if I had to choose between all of metric and all of imperial then I'd ditch Fahrenheit in a heartbeat, but it's not often in my day to day life that I think I'd ever use any temperature outside of (approximately) -15°C and 35°C. Therefore Fahrenheit in that specific regard offers more granularity and a nice 0-100 type of temperature scale for the temperatures I'd see on a day to day basis.

On a day-to-day base it's really just about what you're being used to. Who cares about granularity in weather forecast? You get out of the shadow and it's too hot for a jacket.
Also, weather is not the only daily use of tenperature, look at cooking and baking where younhave much higher temperatures and always go beyond 100°F.
