Yeah it really only matters what you are comfortable with, if you get units you aren’t comfortable with then it gets confusing. I almost feel like metric folk don’t realize that the USA is like 50 EU states in size, and this disconnect causes them some rage at seeing imperial units. At the human level I still can’t comprehend Celsius, mostly cuz those numbers have meanings in fahrenheit, sure makes for some cognitive dissonance to heard 35 degrees thinking you would need snow gear to hearing it’s unbearably hot.
