The gradations are in micrometres.
LC= Value of one main scale division Total number of divisions on vernier
A calliper is any tool with a claw-like shape/movement, like a calliper micrometer, which is used to measure the size of small parts with high accuracy, or the calliper brakes on a bicycle or a car with disc brakes.
For finding accurate volume of a pencil use a vernier calliper, which measures diameter up to two significant figures. For finding volume of a pencil you will need radius (r) and length (L) of the pencil. V = 3.14 r²L
A vernier caliper can typically measure lengths ranging from 0 to 6 inches (0 to 150 millimeters) accurately. The minimum length that can be measured with a vernier caliper is usually around 0.02 inches (0.1 millimeters) due to the precision of its scale divisions. The maximum length that can be measured depends on the specific design and size of the caliper, but it is generally around 6 inches (150 millimeters) for standard models.
.02mm
The zero error of vernier calliper is defined as :-The zero error is equal to the distance between the zero of the main scale and the zero of the vernier scale.
The gradations are in micrometres.
It can, but the vernier is capable of a more accurate reading.
0.02
well it depends on what actual type it is, for there is many versions of the vernier and it can be inchs feet and centimeters

look for the zero marking in the main scale and focus your eyes to the mark below it.
Because they were invented by Pierre Vernier in 1631.
