What does caliber measure in firearms?

Caliber primarily denotes the internal diameter of a gun barrel and can also express barrel length as a multiple of that diameter.

What is a micrometer used for?

A micrometer measures extremely small lengths, useful for sizes of microorganisms, coating thicknesses, and microscale engineering dimensions.

Can the caliber to micrometer conversion be used for all length measurements?

No, since caliber relates specifically to firearm bore dimensions, its conversion may not apply accurately to general length measurements without context.
