Which tool is commonly used to measure small dimensions in manufacturing?

Calipers are specifically designed to measure small dimensions with a high degree of accuracy and precision, making them uniquely suited for tasks in manufacturing. They can measure both internal and external dimensions, as well as depths, allowing for versatile applications. The design of calipers enables them to read measurements in much finer increments than other measuring tools, which is essential for quality control in manufacturing processes.

While protractors are effective for measuring angles, tape measures and rulers are generally utilized for longer lengths and may not offer the precision needed for smaller dimensions. Rulers, although they can be used for measuring lengths, typically do not provide the same level of accuracy in small measurements as calipers do. Therefore, for the specific requirement of measuring small dimensions, calipers are the most appropriate and widely accepted tool in the manufacturing industry.
