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 mostly used in traditional British measurements.

Why use astronomical units for length?

Astronomical units provide a convenient scale to express distances within the Solar System, avoiding very large metre values commonly found in space measurements.

Is converting barleycorn to astronomical units practical?

Due to the extreme difference in scale, this conversion is mainly academic or illustrative, not typically practical for scientific or engineering calculations.
