What is a picometer used for?

A picometer is an SI unit of length used to describe very small distances at atomic and molecular scales, such as bond lengths and atomic radii.

What does a parsec measure?

A parsec is an astronomical unit of length used to express distances between stars and celestial objects, defined by the distance at which 1 AU subtends one arcsecond.

Why convert picometers to parsecs?

Converting between picometers and parsecs helps relate atomic-scale measurements to astronomical distances, useful for scientific analysis bridging vastly different length scales.
