worldspace rotation of a child gameobject

How can i determine the worldspace rotation of a child gameobject, that is independent of the parent gameobject rotations ?

I have a a gameobject with a child gameobject. the parent gameobject rotates 360 degrees (x axis) but from the child gameobject i want to know what the world space rotation is ? independent of what the rotation of the parent is ?

Transform.rotation

Is in world space, Docs.

Transform.eulerAngles

Like robertbu said, Docs.
