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. Micrometers (µm) measure cells (human cell = ~10–30 µm), bacteria (1–5 µm), and microelectronics. Pollen grains are ~15–100 µm wide.
To convert between Chain (ch) and Micrometer (µm), use the following formulas:
1 Chain (ch) = 20116800.000000004 Micrometer (µm)
1 Micrometer (µm) = 4.970969537898671e-8 Chain (ch)
1 ch = 1 * 20116800.000000004 µm = 20116800.000000004 µm
5 ch = 5 * 20116800.000000004 µm = 100584000.00000001 µm
10 ch = 10 * 20116800.000000004 µm = 201168000.00000003 µm
20 ch = 20 * 20116800.000000004 µm = 402336000.00000006 µm
50 ch = 50 * 20116800.000000004 µm = 1005840000.0000002 µm
100 ch = 100 * 20116800.000000004 µm = 2011680000.0000005 µm
