Units and Measurements

A screw gauge has a least count of 0.01 mm and there are 50 divisions in its circular scale. The pitch of the screw gauge is:

  1. A.0.01 mm
  2. B.0.25 mm
  3. C.0.5 mm✓
  4. D.1.0 mm

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
