About these units
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.
Rod (rd)
A rod, equal to 16½ feet (or 5.0292 meters), is a historic English unit that dates back to agricultural practices and land surveying in medieval Europe. Originally based on the length of a stiff pole used by farmers to control oxen, the rod became standardized and deeply embedded in systems of land division. Surveyors valued rods because they integrate neatly with other land-measurement units: 4 rods make a chain, and 160 square rods make an acre. These relationships simplified calculations when establishing property boundaries or mapping rural land parcels. Although no longer widely used for modern surveying—supplanted by meters or feet—the rod lives on in historical land deeds, mining claims, and older legal documents. Understanding rods can be essential for interpreting pre-modern land descriptions that still influence property law today.
