Jangka Sorong (Vernier Caliper)

A vernier caliper is a measuring device used to precisely measure linear dimensions.

It is a very useful tool to use when measuring the diameter of  a round objects like cylinders because the measuring jaws can be secured on either side of the circumference.

Vernier calipers have both a fixed main scale and a moving vernier scale.

The main scale is graduated in either millimetres or tenths of an inch.

The vernier scale allows much more precise readings to be taken (usually to the nearest 0.02mm or 0.001 inch) in comparison to a standard ruler (which only measures to th nearest 1mm or 0.25 inch).

The vernier scale was invented by French mathematician Pierre Vernier in 1631.

As part of the vernier caliper, it is used together with the main scale, and helps to provide very precise measurements.

Vernier calipers usually show either imperial or metric measurements, but some measure in both.


The range (sometimes called maximum capacity) of a vernier caliper is the difference between the largest value and the smallest value that the caliper can measure. It is equal to the length of the main scale.

Most vernier calipers have a range of 6 inches (300mm), although calipers with smaller and larger ranges are also available.
