Calipers are precision measuring instruments used to measure the dimensions of objects, such as length, width, depth, and internal or external diameters. They consist of two adjustable jaws, one fixed and one movable, that can be positioned around or within the object being measured. Calipers can be digital, dial, or vernier, with measurements typically displayed in millimeters or inches. They are essential tools in fields like engineering, metalworking, and woodworking, where precise measurements are crucial.
