Key Differences
Calipers are precision instruments used for measuring the distance between two opposite sides of an object. They come in various forms, including vernier, dial, and digital, offering precise measurements for engineering, manufacturing, and woodworking applications. On the other hand, caliber refers to the internal diameter or bore of a gun barrel, or the diameter of a projectile used in firearms. It is a critical specification for firearms and ammunition, determining the size and type of projectile that can be fired.
While calipers are versatile tools used across many industries for detailed measurements, caliber is a specific term used primarily in the context of firearms and ammunition. Caliber measurements are crucial for the safe and effective operation of firearms, ensuring that the ammunition matches the firearm's specifications. In contrast, calipers are essential for quality control, design, and manufacturing processes, providing accurate measurements that can be critical to the success of a project.
Calipers can measure a wide range of dimensions, including internal, external, depth, and step measurements, making them indispensable in settings that require high precision. Caliber, however, is used to classify firearms and ammunition, playing a vital role in the selection process for shooters and manufacturers, focusing on the ballistic performance and compatibility of ammunition with a particular firearm.
The accuracy of calipers can be affected by factors such as the skill of the user, the condition of the tool, and the material being measured. Meanwhile, the significance of caliber lies in its direct impact on the power, range, and accuracy of a firearm, with larger calibers generally offering more power but also greater recoil.
Despite their differences, both calipers and caliber highlight the importance of precise measurements, whether in the field of manufacturing and engineering or in the selection and use of firearms. Accuracy, whether it's in creating components that fit perfectly together or choosing the right ammunition for a specific purpose, is critical in ensuring safety, performance, and success.

Calipers
A caliper (British spelling also calliper, or in plurale tantum sense a pair of calipers) is a device used to measure the dimensions of an object. Many types of calipers permit reading out a measurement on a ruled scale, a dial, or a digital display.
Caliber
In guns, particularly firearms, caliber (or calibre in British English; sometimes abbreviated as "cal") is the specified nominal internal diameter of the gun barrel bore - regardless of how or where the bore is measured and whether the finished bore matches that specification. It is measured in inches or in millimeters.
