What is the purpose of calipers in engineering?

Calipers serve a specific function in engineering by providing precise measurements of distance or thickness, which is essential for various design and manufacturing processes. The adjustable jaws of calipers allow users to measure both external dimensions (like the diameter of a rod) and internal dimensions (like the width of a hole) with high accuracy. This versatility is particularly beneficial in ensuring that components fit together correctly in assemblies, which is crucial in engineering applications.

The design of calipers, whether they are vernier, dial, or digital, enhances their ability to deliver exact measurements, making them indispensable tools in fields like mechanical engineering, construction, and quality control. Their role in measuring distance or thickness accurately aligns with the precise specifications often required in engineering projects.
