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). 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 Hand (hh) and Nanometer (nm), use the following formulas:
1 Hand (hh) = 101599999.99999999 Nanometer (nm)
1 Nanometer (nm) = 9.842519685039372e-9 Hand (hh)
1 hh = 1 * 101599999.99999999 nm = 101599999.99999999 nm
2 hh = 2 * 101599999.99999999 nm = 203199999.99999997 nm
5 hh = 5 * 101599999.99999999 nm = 507999999.99999994 nm
10 hh = 10 * 101599999.99999999 nm = 1015999999.9999999 nm
15 hh = 15 * 101599999.99999999 nm = 1523999999.9999998 nm
20 hh = 20 * 101599999.99999999 nm = 2031999999.9999998 nm
