What is caliber as a unit of length?

Caliber refers to the internal diameter or barrel length of a firearm, expressed in inches or millimeters, and can quantify barrel length as multiples of its bore diameter.

What does the astronomical unit measure?

The astronomical unit is a length unit defined as exactly 149,597,870,700 metres, commonly used to express distances within the Solar System, such as planetary orbits.

Why convert caliber to astronomical units?

Conversions from caliber to astronomical units are used primarily for theoretical or educational purposes to relate very small firearm lengths to vast celestial distances.
