I know that's bad terminology, but I always envision integration as counting the number of squares in units XYZ below a curve from a to b. The size of the square depends on the units on the axes.

?

nope: radians are without units. That was why I was tricked in the first place. See Dieter's reply.

So if you want to regard the curve in respect to units: the y axis has no units and the x axis is in radian (no unit) or in degrees. So no square degrees.
