i have a stepper motor of step angle 1.8 degree which i have
micro-stepped so that its angular movement is 0.01degree per pulse.how
can i convert this into a linear motion?the linear movement is supposed
to be in the order of micro meter.(i thought of rack pinion arrangement
but then how to do it was confusing).so help me as soon as possible
friends.

Think of a screw thread rod with a pitch of say 1 mm. 360 deg = 1000 micrometer advance of a nut. 1.8 degree = 5 micrometer advance. Get it?

I used a standard 1 inch (12tpi) bolt that I used for adjusting a roller. And like Brian states I had the following: one revolution of the screw = 1"/12tpi = 0.083" linear travel (for my needs) 1.8 degree = 0.083" / (360 / 1.8) = 0.000128 inch linear travel
