About these units
Zhang (Chinese) (zhang)
Ten chi, 10/3 m (about 3.33 m) in the modern market system.
Ten chi made one zhang, so the unit was always a measure of the human scale of buildings and cloth rather than of personal reach. It turns up in Chinese architecture as a way to describe the width of a bay and the height of walls and pillars. Since the chi itself changed from dynasty to dynasty, the zhang changed in step with it and had no independent standard.
Republican law fixed it twice. In 1915 the Republic of China set it at about 3.2 m, and in 1930 the figure was revised to exactly 10/3 m, about 3.33 m, which is the value used here. Mainland China uses it rarely today, and everyday speech tends toward meters. The Japanese jo is built the same way from ten shaku, giving about 3.03 m, which shows how a shared structure produced different lengths.
1 zhang (Chinese) = 3.333333333 meters (approximately).

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).
