Vernier calipers are used to measure length when quite accurate measurement is required, but not such accuracy as to require a micrometer.
A micrometer (device) measures distance more accurately with more precision than a vernier or a tape measure. It is much cheaper than using an electron microscope, which can measure, with calibration, a length in the order of 1E-9 meter. A micrometer (unit) is equal to 1E-6 meter.
Vernier calipers is more convenient to use compared to the external and internal calipers because vernier caliper by its own could be used as external and internal calipers. When using Vernier caliper you can identify the measurement withtout using ruler, meter stick etc. but the internal and external calipers rely on measuring tools to know the exact measurement... (*Ivan Richmond Jumawan*).
There are several conclusion for Vernier calipers. One is that in comparison to other tools like micrometers, they have less accuracy. Regardless, the Vernier calipers seem to allow a larger measurement range leading to better versatility.

The zero error in the vernier calipers and micrometer screw gauge when the O mark on the main scale is not in line with the pointer.

Because the secondary scale, which gave the calipers it accuracy, was designed by the French mathematician Pierre Vernier.
Micrometer is having a ratchet to rotate which is pre-loaded to get standard thrust while measurement, whereas in the case of a vernier the accuracy of measurement depend on the pressure each individual applying while the measurement.
The most compelling reason to select the micrometer Screw over the Vernier caliper is the guarantee that when measuring a flexible surface, the same amount of pressure is applied between samples. The Vernier caliper has the ability to measure internal and externally, but if precision is required, the micrometer screw is the tool of choice.
vernier calliper scale. give us reading upto two places right side from decimal
Just say it in Latin: Micrometer. Micro = small, Meter is measure. Vernier calipers do a good job also.
A micrometer , sometimes known as a micrometer screw gauge, is a device incorporating a calibrated screw used widely for precise measurement of small distances in mechanical engineering and machining as well as most mechanical trades, along with other metrological instruments such as dial, vernier, and digital calipers. Micrometers are similar in use to vernier calipers but are more precise although the modern digital caliper has blurred the distinction between them.A micrometer is also used to measure the diameter of very small objects that a vernier calliper can't measure for example a screw or a piece of wire.This instrument is mainly used by mechanics.
It is the scale on a micrometer.
I guess it is found by vernier as it works on vernier theory -Manasa
Vernier Caliper are made with different materials even plastic vernier calipers are also available in market however generally stainless steel is used in making of vernier calipers
