What does 1 petameter represent?

One petameter equals 10^15 metres, representing extremely large distances such as fractions of a light-year.

Why convert petameters to Bohr radii?

This conversion enables bridging astronomical and atomic scales, useful in theoretical physics and computational chemistry.

Can I use this for practical measurements?

Due to the huge scale difference, this conversion is mostly for theoretical or computational purposes, not practical measurements.
