What is a picometer used for?

A picometer is an SI unit used to measure extremely small distances such as atomic bond lengths and subnanometre spatial measurements.

Why use astronomical units in measurements?

Astronomical units provide a convenient length scale for distances within the Solar System, such as planetary orbits and spacecraft trajectories.

Can I convert from picometers to astronomical units for practical measurements?

Due to the vast scale difference, results are extremely small and are mostly useful for scientific understanding rather than practical measurement.
