How to set Unit like this "360 deg/r"?

[jlee-10-11-12]

I have some parametric in motor torque calculation, for example: motor speed: 2000 Pulse/round, or 360 deg/r.

but i can't find unit of "degree" or "deg/r" in MathCAD Prime 4.0. 

How to add costume unit, or how to give the unit deg/r to value?

I don't think you need a custom unit

Thank you for your help, i tried as you teach me.

But why my "pulse" in fifth line is not blue color, and in last line it said “Variable undefined”?

The answer is "labels". A name with a different label is considered distinct. Click in your definition of pulse. On the math tab, choose labels, and select Unit. The definition will turn blue, and then the rest will work.
