The internal jaws of a vernier caliper are used to measure the internal diameter of a hollow cylinder or pipe. 

Explanation

  • The internal jaws of a vernier caliper are designed to rest on the internal walls of a hollow cylinder or tube. 
  • The diameter of the open end of the cylinder or tube should be roughly equal to the internal diameter so that the walls don't interfere with the jaws. 
  • A vernier caliper can also be used to measure the external diameter of a tube, the internal diameter of a mug, and the depth of a small bottle.
