What speed units does the rotator node use?

I’m trying to align a texture to rotate within a material at the exact speed of a blueprint which is using the rotating movement component. In the rotating movement component, units are “degrees per second” but in the material rotator node it uses something else.

Ok, so I do know this question is nearly two years old, but since it appears first in my google search for that request, I am going to answer it : the unit is radians / second. 360° = pi radians, I’ll leave the maths to you from here.
