how to measure pitch in vernier calliper

Somnath physics · Accepted Answer

Pitch is defined for screw gauges
where it is defined as the forward movement of the rotating drum
when it undergoes a complete rotation

As in Vernier calipers there are
no rotating screw therefore there is no pitch, however the minimum
measurable forward movement of the vernier scale is 1 mm in the
main scale Thus its pitch can be said as 1 mm
