What is a petameter used for?

A petameter measures extremely large distances, useful for expressing sizes of interstellar structures and nearby star distances on the order of fractions of a light-year.

What does the Planck length represent?

The Planck length is the fundamental quantum scale defined by physical constants, marking where quantum gravitational effects dominate and classical space concepts may break down.

Why convert petameters to Planck lengths?

Converting petameters to Planck lengths allows scientists to relate vast astronomical distances to the smallest meaningful physical lengths for theoretical and quantum gravity analyses.
