Picometers (pm) describe atomic radii and X-ray wavelengths. A hydrogen atom is ~53 pm wide. Used in crystallography and semiconductor engineering. 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 Picometer (pm) and Chain (ch), use the following formulas:
1 Picometer (pm) = 4.9709695378986716e-14 Chain (ch)
1 Chain (ch) = 20116800000000 Picometer (pm)
100 pm = 100 * 4.9709695378986716e-14 ch = 4.9709695378986715e-12 ch
500 pm = 500 * 4.9709695378986716e-14 ch = 2.485484768949336e-11 ch
1000 pm = 1000 * 4.9709695378986716e-14 ch = 4.970969537898672e-11 ch
5000 pm = 5000 * 4.9709695378986716e-14 ch = 2.485484768949336e-10 ch
