What is an attometer?

An attometer (am) is an SI unit of length equal to 10^-18 metres, used to express extremely small distances relevant in particle and nuclear physics.

What is a petameter used for?

A petameter (Pm) equals 10^15 metres and is used for expressing very large distances such as those between nearby stars or interstellar structures.

Why convert attometers to petameters?

Converting attometers to petameters helps bridge length scales from the subatomic level to astronomical distances, facilitating scientific communication across disciplines.
