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. Picometers (pm) describe atomic radii and X-ray wavelengths. A hydrogen atom is ~53 pm wide. Used in crystallography and semiconductor engineering.
To convert between Chain (ch) and Picometer (pm), use the following formulas:
1 Chain (ch) = 20116800000000 Picometer (pm)
1 Picometer (pm) = 4.9709695378986716e-14 Chain (ch)
1 ch = 1 * 20116800000000 pm = 20116800000000 pm
5 ch = 5 * 20116800000000 pm = 100584000000000 pm
10 ch = 10 * 20116800000000 pm = 201168000000000 pm
20 ch = 20 * 20116800000000 pm = 402336000000000 pm
50 ch = 50 * 20116800000000 pm = 1005840000000000 pm
100 ch = 100 * 20116800000000 pm = 2011680000000000 pm
