Despite American culture being universal everywhere around the world, I’ve not really seen anyone outside of the Anglosphere use feet and inches to express their height, let alone pounds for weight or degrees Fahrenheit. Even Poland, which is very pro-US and the birthplace of Fahrenheit himself, does not use degrees Fahrenheit in any capacity. Why is that?
