Just FYI, the symbol you're using is an "ordinal indicator" (it has a tiny line below it), e.g. 1º means "first" according to Wikipedia (I copied the symbol and put it in duckduckgo). TIL. For me, on Linux with US-international keyboard (with dead keys), the degrees symbol is on AltGr+Shift+0 (and then either a letter, like å, or space to just make the degrees symbol).
