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 and mainly used in traditional British measurements.

What is a megameter [Mm] used for?

A megameter is an SI derived unit equal to one million meters and is used to describe large terrestrial and planetary distances in scientific and engineering contexts.

Why convert barleycorn to megameter?

This conversion helps translate old British length units into modern scientific units, useful for integrating historical measurements with planetary-scale data or engineering projects.
