Micrometers (µm) measure cells (human cell = ~10–30 µm), bacteria (1–5 µm), and microelectronics. Pollen grains are ~15–100 µm wide. 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 Micrometer (µm) and Chain (ch), use the following formulas:
1 Micrometer (µm) = 4.970969537898671e-8 Chain (ch)
1 Chain (ch) = 20116800.000000004 Micrometer (µm)
1 µm = 1 * 4.970969537898671e-8 ch = 4.970969537898671e-8 ch
10 µm = 10 * 4.970969537898671e-8 ch = 4.970969537898672e-7 ch
50 µm = 50 * 4.970969537898671e-8 ch = 0.0000024854847689493354 ch
100 µm = 100 * 4.970969537898671e-8 ch = 0.000004970969537898671 ch
500 µm = 500 * 4.970969537898671e-8 ch = 0.000024854847689493357 ch
