Question

what is vernier calipers

Answer 1

A vernier caliper is a measuring device used to precisely measure linear dimensions.


It is a very useful tool to use when measuring the diameter of  a round objects like cylinders because the measuring jaws can be secured on either side of the circumference

Vernier calipers have both a fixed main scale and a moving vernier scale.

 

The main scale is graduated in either millimetres or tenths of an inch.  

 

The vernier scale allows much more precise readings to be taken (usually to the nearest 0.02mm or 0.001 inch) in comparison to a standard ruler (which only measures to th nearest 1mm or 0.25 inch).
