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. 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.
To convert between Millimeter (mm) and Chain (ch), use the following formulas:
1 Millimeter (mm) = 0.000049709695378986714 Chain (ch)
1 Chain (ch) = 20116.8 Millimeter (mm)
1 mm = 1 * 0.000049709695378986714 ch = 0.000049709695378986714 ch
8 mm = 8 * 0.000049709695378986714 ch = 0.0003976775630318937 ch
30 mm = 30 * 0.000049709695378986714 ch = 0.0014912908613696014 ch
90 mm = 90 * 0.000049709695378986714 ch = 0.004473872584108804 ch
120 mm = 120 * 0.000049709695378986714 ch = 0.005965163445478406 ch
245 mm = 245 * 0.000049709695378986714 ch = 0.012178875367851744 ch
559 mm = 559 * 0.000049709695378986714 ch = 0.027787719716853572 ch
