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). The Thou (also called Mil) is essential in precision engineering and manufacturing. For context, a standard sheet of paper is about 100 thou thick, while human hair measures approximately 20-30 thou in diameter. This unit is critical in machining tolerances, PCB design, and automotive engineering where exact measurements are crucial.
To convert between Hand (hh) and Thou (Mil) (mil), use the following formulas:
1 Hand (hh) = 3999.9999999999995 Thou (Mil) (mil)
1 Thou (Mil) (mil) = 0.00025 Hand (hh)
1 hh = 1 * 3999.9999999999995 mil = 3999.9999999999995 mil
2 hh = 2 * 3999.9999999999995 mil = 7999.999999999999 mil
5 hh = 5 * 3999.9999999999995 mil = 19999.999999999996 mil
10 hh = 10 * 3999.9999999999995 mil = 39999.99999999999 mil
15 hh = 15 * 3999.9999999999995 mil = 59999.99999999999 mil
20 hh = 20 * 3999.9999999999995 mil = 79999.99999999999 mil
| Hand (hh) | Thou (Mil) (mil) |
|---|---|
| 1 hh | 3999.9999999999995 mil |
| 2 hh | 7999.999999999999 mil |
| 5 hh | 19999.999999999996 mil |
| 10 hh | 39999.99999999999 mil |
| 15 hh | 59999.99999999999 mil |
| 20 hh | 79999.99999999999 mil |
