What does one petameter equal in meters?

One petameter corresponds to 10^15 meters, making it suitable for expressing very large distances.

Why convert petameters to attometers?

This conversion helps bridge understanding from massive astronomical distances to subatomic scales used in physics.

Is this conversion commonly used in practical measurements?

No, the enormous scale difference makes the conversion mainly theoretical or for scientific illustration.
