A calliper is a precision measuring instrument used to determine the distance between two sides of an object. 📏 Think of it as a super-accurate ruler that can measure the thickness or diameter of things with great precision. It has two jaws that can be adjusted to fit around or inside an object. Callipers are used in engineering, manufacturing, and medicine. ⚙️ They help ensure parts fit together perfectly or to measure the size of something accurately.
