What is a parsec used for?

A parsec is mainly used to express distances between stars and celestial objects in astronomy, such as stellar distances from parallax measurements and distances to nearby galaxies.

Why convert parsecs to nanometers?

Converting parsecs to nanometers enables comparisons between very large astronomical distances and very small nanoscale dimensions, which is useful in interdisciplinary research and theoretical physics.

Is it practical to measure astronomical distances in nanometers?

No, nanometers are too small for practical astronomical measurements; such conversions are mainly theoretical or for computational purposes.
