Why would anyone watch a pewdiepie video?

Epic projection comment. How very much your multi paragraph reply screams “I don’t care”.

You do realize the reason fahrenheit is set up that way, is based on the human perception of temperature. 0-100 is the general range or cold to hot.

That is not why fahrenheit works the way it does. This is something Americans have appropriated as a silly and poor excuse for using it. “cold” and “hot” are completely arbitrary and subjective terms, and the 0-100 range is as arbitrary.

Metric is good for science, but not ideal for casual everyday usage of hot and cold.

That will come as a surprise to the billions of people using it every day for exactly that purpose. You are projecting your own ignorance over billions of people, because you yourself have no idea how it works.
