Ahhh...yes...you are quite correct P901...but...

See the "Unit of Measure"? That 'mm' means millimeters, not inches... LoL

So on 3/8-12 ACME, that's 1/12 inch per turn = 0.08333" * 25.4 = 2.1166mm per turn.

To turn 1mm, we get 200 steps per turn = 2.1166mm per turn => 200/2.1166 = 94.49 turns per mm.
