I think the author may have simply been a little confused - perhaps they were meaning radians? I seem to remember that pi gets involved there somewhere, though I'm no math whizz.
Probably why I stink so much at 3D modeling 
There are countless measurements for angles in use today as it is
From Unit To Unit Multiply By
degree (°) (°) 1.000 000 E+00
grade (gr) (°) 9.000 000 E-01
minute (min) (°) 1.666 667 E-02
quadrant (quad) (°) 9.000 000 E+01
radian (rad) (°) 5.729 578 E+01
revolution (rev) (°) 3.600 000 E+02
second (s) (°) 2.777 778 E-04
No doubt one of these wil match the theory put forward
Remeber:
If you think you have an original idea you simply haven't done enough research. 
*EDIT*
Radians explained
Adiel: How can you defend a country where 5 percent of the people control 95 percent of the wealth?
Lisa: I'm defending a country where people can think and act and worship any way they want!
Adiel: Cannot!
Lisa: Can to!
Adiel: Cannot!
Lisa: Can to!
Homer: Please, please, kids; stop fighting. Maybe Lisa is right about America being the land of opportunity, maybe Adiel has a point about the machinery of capitalism being oiled with the blood of the workers.
