About these units
Hand (hh)
Exactly 4 inches (10.16 cm). Used almost only to measure the height of horses at the withers.
Horse people still say a mare stands fifteen hands, and the word is the same Old English hand that names the body part. The unit was first the breadth of a hand, with or without the thumb, or the height of a clenched fist, and the figure varied from person to person. Ancient Egyptian cubit-rods show a comparable hand of five digits, roughly 94 mm. In England, a Horses Act of 1540 under Henry VIII fixed the hand at four inches, and some later dictionaries still muddled it with the three-inch handsbreadth.
The figure used here is exactly 4 inches, or 10.16 cm. Fractions are counted in inches, not tenths, so a height written 15.2 means fifteen hands and two inches, which is 62 inches, and 15.3 is followed directly by 16.0. The height is taken at the withers, the ridge between the shoulder blades. The unit survives for horses and ponies in the United States, Canada, the United Kingdom, Ireland, Australia and New Zealand, while continental Europe and international equestrian competition use metric.
1 hand = 0.1016 meters (exactly).

Kilometer (km)
1,000 meters. The standard unit for road distances in most countries.
A name for 1,000 meters took a while to settle. In 1793 France's National Convention made the metre the sole French unit of length, and the first proposed name for the thousand-metre multiple was millaire. Everyday French usage then leaned on the myriametre, 10,000 meters, well into the 1800s. The Netherlands adopted the kilometre in 1817, under the local name mijl, and made it the only official unit of that size in 1867. In 1935 the CIPM dropped the myria- prefix, which left the kilometre as the standard unit for road-scale distances.
Kilo- is the SI prefix for a thousand, and the kilometre is now the preferred unit for land distances in most of the world, with the United States, the United Kingdom and Liberia among those that still use the mile. One kilometre is about 0.621 mile. The main span of Lisbon's 25 de Abril Bridge, at 1.013 km, gives a sense of the scale. Even its pronunciation has been argued over: in 1970 Australia's Metric Conversion Board made stress on the first syllable official, although Prime Minister Gough Whitlam argued for stress on the second. Military slang in several countries calls it a klick.
1 kilometer = 1,000 meters (exactly).
