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. 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 Nanometer (nm) and Chain (ch), use the following formulas:
1 Nanometer (nm) = 4.970969537898672e-11 Chain (ch)
1 Chain (ch) = 20116800000 Nanometer (nm)
1 nm = 1 * 4.970969537898672e-11 ch = 4.970969537898672e-11 ch
10 nm = 10 * 4.970969537898672e-11 ch = 4.970969537898672e-10 ch
100 nm = 100 * 4.970969537898672e-11 ch = 4.970969537898672e-9 ch
500 nm = 500 * 4.970969537898672e-11 ch = 2.485484768949336e-8 ch
