What does one light year represent?

A light year is the distance light travels in a vacuum during one Julian year, about 9.4607 × 10^15 metres.

What is the Bohr radius used for?

The Bohr radius represents the most probable distance between the nucleus and electron in hydrogen’s ground state and is used in quantum chemistry and atomic-scale calculations.

Can this converter be used for practical measurements?

Due to the extreme difference in scale, this conversion is mostly practical for theoretical, educational, and research purposes rather than everyday use.
