Vernier calipers are precision measuring tools used to measure the internal and external dimensions of objects.
Consists of two jaws, one fixed and one movable
Has a scale and a vernier scale for precise measurements
Used in engineering, machining, and scientific research
Can measure length, depth, and thickness
Example: Used to measure the diameter of a bolt or the thickness of a sheet of metal
The least count of vernier calipers is the smallest measurement that can be read on the scale.
The least count is determined by the number of divisions on the vernier scale and the main scale.
For example, if the main scale has 10 divisions and the vernier scale has 9 divisions, the least count would be 0.1 mm.
The least count can vary depending on the type and brand of the vernier caliper.
