Ruler Calipers

Ruler Calipers
Ruler Calipers
Compare the ruler, Vernier Caliper and micrometer caliper in their accuracy of measurement. Which is the most?

help me is this question.. thanks in advance.

the accuracy of a ruler is limited by the eye's ability to see the spacing of the measurement marks and to line up the item to be measured with the marks on the ruler. In practical terms, a measurement accuracy of about 0.010" is possible by someone with very good eyesight.

A vernier caliper is limited by the eye's ability to line up the marks on the vernier. An accuracy of 0.001" is achievable with good vision and a decent "feel".

The third instrument is a micrometer not a micrometer caliper. A micrometer uses a very accurate screw thread to get the measurement. It is still dependent on the operator's ability to visually differentiate the vernier scale marks and to achieve a repeatable "feel". Accuracies of 0.0001" are obtainable.

The accuracy of both the caliper and the micrometer are affected by calibration.
