A Vernier Scale is a measuring instrument that enhances the precision of measurements taken with a standard ruler or caliper. It consists of a main scale and a sliding scale, known as the vernier scale, which allows users to read measurements more accurately than with the main scale alone. The vernier scale typically provides measurements to a fraction of a millimeter or inch, making it useful in various fields such as engineering and woodworking. The design of the Vernier Scale was developed by the French mathematician Pierre Vernier in the 17th century. It is commonly found in tools like calipers and micrometers, which are essential for tasks requiring high precision. By aligning the scales, users can determine measurements with greater accuracy, improving the quality of their work.
