OK, OK. Degree Celsius is a so-called Derived SI Unit. :-)

they wouldn't overload unit names, right? :-)

There's no contradiction, as far as I see: degree comes

Oooh, here's a good one!
There *are* no unit names for angles. Angles are unitless numbers.
So to be strict, the SI unit for heading must be the radian. :)

Those are Grads. I've heard that the military use them ... but I haven't
seen any evidence of it.
Infantery and artillery use 0-6400 mil (called Strich over here), NBC also
uses

Actually, there's a very good reason why we use a 360 degree circle.
This number has loads of small integer divisors. What's the inner
angle between the walls of a 4-sided room? 90
