About Chain (ch) and Millimeter (mm) Units

The Chain (Gunter's chain) was fundamental in surveying the American frontier. Measuring 66 feet (4 rods), it's the length of a cricket pitch. Ten square chains make an acre. Modern surveyors still reference chains in legal descriptions, and the unit remains visible in rural road layouts across the US. The Millimeter (mm) is perfect for very small measurements like the thickness of a credit card (0.76 mm), the diameter of a pencil lead (0.5-0.7 mm), or the size of small hardware components. Commonly used in engineering, jewelry design and manufacturing.
