Yes, they are handy instruments.
Because the secondary scale, which gave the calipers it accuracy, was designed by the French mathematician Pierre Vernier.
I guess it is found by vernier as it works on vernier theory -Manasa
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.
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
A caliper is a tool that can be used to measure both internal and external diameter accurately. It consists of two arms with measuring jaws that can be adjusted to fit the size of the object being measured. The different types of calipers include digital, dial, and Vernier calipers.
Vernier calipers are in use in machine shops throughout the world. Of course, they are gradually being replaced by digital calipers but, plenty are still in use in England.
The modern vernier caliper reads to thousandths of an inch
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*).
Vernier Calipers are instruments that are used measure length. It is an instrument that provides a digit of accuracy.
Slide calipers was invented by the French mathematician Pierre Vernier.It was known as Vernier calipers.

A Vernier detects small differences in measurements with precision. It is widely used in scientific instruments such as calipers and micrometers to provide accurate readings for various applications like engineering, physics, and chemistry.
