What is a micrometer used for?

A micrometer is a unit of length used to measure very small dimensions such as those of microorganisms, cell sizes, and thicknesses of coatings or films.

What does the Roman actus measure?

The Roman actus is an ancient unit of length used mainly for land measurement and surveying in Roman times, also serving as the side of a standard square for area definition.

Can this converter be used for precise modern measurements?

No, because the Roman actus is historical and approximate, it is not suitable for precise contemporary measurement needs.
