This matches the spec, https://drafts.csswg.org/css-values/#angles, which says: > All <angle> units are compatible, and deg is their canonical unit. And https://drafts.csswg.org/css-values/#compat, which says: >When serializing computed values [...], compatible units [...] are converted into a single canonical unit. And also other implementations (Blink always serializes angles as degrees in computed style for example). Also allows us to get rid of quite a bit of code, and makes computed angle value representation just a number, which is nice.
