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. Nanometers (nm) are critical in nanotechnology, biology (DNA helix = 2 nm wide), and computing (transistors are 3–5 nm). A human hair is ~80,000 nm thick.
To convert between Chain (ch) and Nanometer (nm), use the following formulas:
1 Chain (ch) = 20116800000 Nanometer (nm)
1 Nanometer (nm) = 4.970969537898672e-11 Chain (ch)
1 ch = 1 * 20116800000 nm = 20116800000 nm
5 ch = 5 * 20116800000 nm = 100584000000 nm
10 ch = 10 * 20116800000 nm = 201168000000 nm
20 ch = 20 * 20116800000 nm = 402336000000 nm
50 ch = 50 * 20116800000 nm = 1005840000000 nm
100 ch = 100 * 20116800000 nm = 2011680000000 nm
