About these units
Handbreadth (handbreadth)
The handbreadth, roughly 0.1 meter, represents the width of a human hand with fingers extended. It served as a convenient, body-based subunit for cubits and larger measures. Handbreadths were integral to construction, tailoring, and craftwork, allowing precise division of larger units into manageable increments. In ancient Egyptian, Greek, and Hebrew measurement systems, the handbreadth facilitated scaling and proportioning for artisans and builders. Today, the handbreadth is mainly of historical interest, helping reconstruct ancient architectural plans and understand the human-centered logic of early measurement systems.
Mil (mil)
A mil is an imperial-derived engineering unit equal to one-thousandth of an inch. It is used extensively in manufacturing, machining, and electrical engineering. Printed circuit board (PCB) trace widths, for instance, are often measured in mils because the unit provides a convenient scale for precision without resorting to decimals in inches. Because 1 mil equals 25.4 micrometers, it occupies a scale appropriate for tolerances in industrial production, coatings, film thickness, and gaskets. The mil is especially common in the United States, where certain engineering standards still rely on the imperial system. It provides an intuitive small-scale measurement for technicians accustomed to inches, helping avoid errors that might result from metric conversions.
