If the caliper is properly calibrated, then neither system is more accurate. Accuracy depends on the quality of the measuring, not the unit used.
You would typically use centimeters (cm) or millimeters (mm) to measure the width of a book. These units provide a more precise measurement for smaller objects like books.
A standard Micrometer using the Metric system has a limitation of measuring to within 0.01 (one hundredth of a millimeter) But micrometers provided with a vernier scale on the sleeve in addition to the regular graduations, permit measurements to within 0.001 millimetre to be made on metric micrometers, or 0.0001 inches on inch-system micrometers.
The least count of the vernier can be measured by using the formula stated below. Least count (L.C) = 1 M.S.D - 1 V.S.D Example; vernier scale is constructed by taking 49 main scale divisions dividing them into 50 divisions ie. 49mm divided into 50 parts therfore 1 vsd=49/50 mm=0.98mm 1 MSD=1mm substituting in formula L.C = 1 M.S.D - 1 V.S.D L.C=1-0.98=0.02mm
The smallest unit shown on a metric ruler is typically millimeters (mm). Each millimeter is divided into smaller increments, such as tenths or hundredths of a millimeter, depending on the precision of the ruler. The metric system is based on powers of 10, making conversions between different units straightforward and consistent.
Most metric micrometers have graduations of .01mm (.001"), and some read to .001mm or nearly .0001". Depending on the application, digital and vernier types are available in both. See "LS Starrett Company" or Mitutoyo America Corporation.
A vernier caliper is a precision measuring instrument used to measure dimensions such as length, depth, and internal/external diameters with high accuracy. It features a main scale and a sliding vernier scale, allowing for measurements to be taken with a resolution typically of 0.01 mm or 0.02 mm. The vernier caliper can measure both metric and imperial units, making it versatile for various applications in engineering and manufacturing.
I think this is meant to be "Vernier Caliper". It is an instrument used to measure objects to limits to fine to read by rule. It consists of two parts. ' 1) A metal bar engraved as a rule, with a blade at right angles to one end, so 'L-'-shaped, and ' 2) A block with a similar blade, sliding on the fixed (Part 1), so forming a pair of adjustable jaws brought into contact with the item to be measured. On the slide is another scale, and this is the Vernier part: if it does not have this, the instrument is a caliper but not a Vernier Caliper. This Vernier scale is engraved in such a way that it has a compounding effect on the adjacent fixed rule, so magnifying the measurements to a readable equivalent. ' The inch-series vernier can read to 1/1000", the metric version to (I think), 0.01mm. I stand to be corrected on that last because I have a metric caliper but it is digital, not vernier!
It depends on what you are trying to measure. If you are measuring the length of a car, for example, any reading obtained using vernier callipers is likely to be totally useless. The key is to select a tool that is appropriate to the task.
You would typically use centimeters (cm) or millimeters (mm) to measure the width of a book. These units provide a more precise measurement for smaller objects like books.
Least count of vernier caliper= 1 MSD - 1 VSD. Main scale usually would have 1 mm as the minimum division. Such 9 divisions, ie 9 mm would be divided into ten equal parts in the vernier. So VSD = 0.9 mm Hence the least count = 1 - 0.9 = 0.1 mm If the same is to be given in centimetre, then it will be 0.01 cm.

It can be used to measure internal as well as external dimensions, and depths of features like steps and blind holes, in small components. Nowadays many machinists etc use digital calipers - which are NOT vernier! - that have dual inch/metric units and often dual decimal/vulgar-fraction readings on the inch settings.

A digital vernier is mainly used to measure lengths or distances very accurately. These may be internal or external distances. The distance may be read as either metric or imperial.
The caliper of trammel ranges from 1 inch to 22 inches if you are looking for a Starrett caliper. They also produce calipers in metric measurements also.
