Calipers

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