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.
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.
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.
something that s used to measure to small fractions of a millimetre. I can't believe you dont know a metric capliers
Metric data is any reading which is at least at an interval scale, as opposed to non metric data, which can be nominal or ordinal. Weight, height, distance, revenue, cost etc. are interval scales or above. Hence they are metric data. On the other hand, satisfaction ratings, Yes/No responses, Male/Female readings etc., are non metric data.
The metric system is generally considered more accurate than the British system when using a vernier caliper, as it offers finer measurement increments. The metric system typically provides measurements in millimeters, which allows for more precise readings compared to the British system's inches and fractions of an inch.
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!
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.
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 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.

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
There are many different reliable sources for metric converters. The Convert Now website does metric conversions at no cost, and they are very accurate.

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.
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.
