A caliper is a measuring instrument used to determine the distance between two points. It is typically used to measure the thickness of objects, the diameter of holes, and the length of objects. Calipers come in a variety of shapes and sizes, but the most common type is the vernier caliper. Vernier calipers have a main scale and a vernier scale, which is a smaller scale that slides along the main scale. The vernier scale allows for precise measurements to be made.
Calipers are an essential tool for many different industries, including manufacturing, engineering, and construction. They are also used in scientific research and education. Calipers are relatively inexpensive and easy to use, making them a valuable tool for anyone who needs to make precise measurements.
