Otherwise, learn to convert units like most of us educated people have to do from time to time!</p>

I'm measuring 5.46mm from flat to other side of shaft (relatively shallow D)</p>

(specially when you mix it up a bit with things like
"Shaft Size: 6mm Diameter x 0.715” Length" )
thanks.</p>

5v/12v = 0.4167
368oz-in * 0.4167 = 153oz-in
10RPM * 0.4167 = 4.167RPM.<p>So @ 5v, stall torque is 153oz-in and no load speed is 4.167RPM.</p></p>
