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). Astronomical scale (Moon's orbit = ~0.38 Gm). Useful for space agency data but rarely searched by the public.
To convert between Hand (hh) and Gigameter (Gm), use the following formulas:
1 Hand (hh) = 1.0159999999999999e-10 Gigameter (Gm)
1 Gigameter (Gm) = 9842519685.03937 Hand (hh)
1 hh = 1 * 1.0159999999999999e-10 Gm = 1.0159999999999999e-10 Gm
2 hh = 2 * 1.0159999999999999e-10 Gm = 2.0319999999999998e-10 Gm
5 hh = 5 * 1.0159999999999999e-10 Gm = 5.079999999999999e-10 Gm
10 hh = 10 * 1.0159999999999999e-10 Gm = 1.0159999999999998e-9 Gm
15 hh = 15 * 1.0159999999999999e-10 Gm = 1.524e-9 Gm
20 hh = 20 * 1.0159999999999999e-10 Gm = 2.0319999999999996e-9 Gm
