About these units

Kilometer (km)

Metric (SI)Current unit

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).

Sun (sun)

JapaneseTraditional unit (still used in some regions)

One tenth of a shaku, about 3.03 cm. The Japanese 'inch', still used in carpentry.

Sun is the Japanese reading of the Chinese character for cun, the Chinese inch, which was traditionally the width of a person's thumb at the knuckle. Japan took the whole system over from China, and the sun kept its place as one tenth of the foot-like shaku.

Because the shaku was fixed in 1891 at 10/33 meter, the sun works out to 1/33 meter, about 30.3 millimeters or 1.19 inches. That makes it about 19 percent longer than a modern inch. Before the legal definition, the size drifted slightly between eras and regions, so older measurements in sun carry some uncertainty.

Smaller steps below it, such as the bu, divide it further. Today the sun survives mainly in carpentry, joinery and traditional crafts, where dimensions are still quoted in shaku and sun before being translated into the millimeters on modern rulers.

1 sun = 0.0303030303 meters (approximately).
