What does caliber measure in firearms?

Caliber primarily indicates the internal diameter of a gun barrel, often linked to bore diameter or barrel length multiples.

What is a femtometer typically used to measure?

A femtometer measures extremely small lengths, such as sizes of atomic nuclei and distances within nuclear physics.

Why do conversions from caliber to femtometer result in large numbers?

Because a femtometer expresses extremely tiny distances, converting large bore diameters in caliber produces very large numeric values.
