What is a mil (thou) unit?

A mil, also known as a thou, is a length unit of one thousandth of an inch, used mainly in U.S. manufacturing to measure very small dimensions.

Where is the barleycorn unit still used?

Barleycorn is mainly found in historical British contexts such as traditional shoe sizing, antiques, tailoring, and craft patterns.

Can I use this conversion for precise engineering measurements?

Since barleycorn is a coarser, historic unit, it is not suitable for high-precision engineering conversions but helpful for historical or niche uses.
