The Hand is the standard unit for measuring horse height worldwide. One hand equals exactly 4 inches. For example, an average riding horse stands about 15-16 hands (60-64 inches) tall at the shoulder. This measurement is taken from the ground to the horse's withers (shoulder ridge). 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 Hand (hh) and Picometer (pm), use the following formulas:
1 Hand (hh) = 101600000000 Picometer (pm)
1 Picometer (pm) = 9.84251968503937e-12 Hand (hh)
1 hh = 1 * 101600000000 pm = 101600000000 pm
2 hh = 2 * 101600000000 pm = 203200000000 pm
5 hh = 5 * 101600000000 pm = 508000000000 pm
10 hh = 10 * 101600000000 pm = 1016000000000 pm
15 hh = 15 * 101600000000 pm = 1524000000000 pm
20 hh = 20 * 101600000000 pm = 2032000000000 pm
