What is a barleycorn?

A barleycorn is a historic unit of length equal to one third of an inch, originally based on the length of a grain of barley.

What distances are measured in petameters?

Petameters are used to describe extremely large astronomical distances, such as those between nearby stars or large interstellar structures.

Why convert barleycorn to petameter?

Such conversion helps translate very small traditional British units into large-scale SI units for scientific contexts like astronomy and astrophysics.
