About Converting Hands to Nautical miles
Hand and Nautical mile both measure length. Specifically: A hand is four inches, often used for horse height, and a nautical mile is exactly 1,852 meters.
Formula
nautical miles = hands × 0.0000548596112311
This factor comes from each unit's defined relationship to the category's base unit: 1 hand equals 0.1016 base units, and 1 nautical mile equals 1852 base units, so dividing one by the other gives the direct hand-to-nautical mile factor of 0.0000548596112311.
Simple example
1 hh × 0.00005485961123 = 0.0000548596 nmi
1 hand = 0.0000548596 nautical miles.

History of the Nautical mile
The nautical mile was historically defined as one minute of latitude along a meridian, directly tying sea navigation to the Earth's geometry, which made it practical for chart-based navigation using a ship's known latitude. The International Hydrographic Bureau standardized it at exactly 1,852 meters in 1929, a value close to the traditional latitude-based definitions used by different countries.
Historical origin. Nautical mile was not the invention of a single named person; it developed through the process described above.
