What is a petameter used to measure?

A petameter measures extremely large distances, such as those between nearby stars or large interstellar structures.

Why convert petameters to femtometers?

This conversion helps compare extremely large astronomical distances with extremely small nuclear scales, useful in astrophysics and nuclear physics.

Is this conversion common in everyday life?

No, due to the extreme difference in scales, this conversion is mainly for theoretical or educational purposes.
