What is the unit of rotation in Transform3D? deg? rad?

I am struggling with Transform3D in fusion. I do not know in what unit the rotation is given. In the reference documentation there only info:

"X, Y, Z Rotation: Use these controls to rotate the object around its pivot point. If the
Use Target checkbox is selected, then the rotation is relative to the position of the
target; otherwise, the global axis is use"

I know that rotate is rotating. This is obvious. In the reference documentation there should be information on what is the unit of this rotation: radians? degrees? rotations?

Cone angle is given in degrees. There are 2 more mentions in documentation about degrees, no mention about radians. But it could be rotations too.

Type in 180 and see if it makes half turn, then you know. Degrees and radians are different enough to not mix them up.
