A vernier caliper is a precision measuring instrument used to measure the dimensions of an object with high accuracy. It consists of a main scale and a sliding vernier scale, which allows for precise measurements to be taken. The main scale is marked in millimetres or inches, while the vernier scale provides additional, finer graduations that improve the accuracy of the measurement.
