What is a barleycorn?

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

Why convert barleycorn to Earth's equatorial radius?

To relate traditional British measurements to global geodetic reference values used in mapping, geodesy, and Earth science.

Is barleycorn commonly used today?

While largely historical, barleycorn still appears in British shoe sizing and some tailoring or craft contexts.

Tips & Best Practices

Ensure correct unit selection to avoid conversion errors
Consider the extremely small scale of barleycorn when converting to Earth's equatorial radius
Use the converted values to bridge legacy data with contemporary geospatial references
Be aware of potential rounding effects when working with vastly different unit scales

Limitations

Barleycorn's small size results in very tiny values when expressed in Earth's equatorial radius units
The unit's historical nature means practical applications are limited
Rounding errors can affect precision due to the large scale difference
