About these units
Fen (Chinese) (fen)
One tenth of a cun in the modern market system, 1/300 m (about 3.3 mm).
Smallest of the everyday Chinese length units, the fen shares its character with the ordinary word for a part or a share, which suits a unit defined as one hundredth of a chi. Older descriptions tie its size to the width of a grain of millet, so it was never a fixed physical quantity in antiquity. It had little use for long distances and appeared mainly in carpentry, tailoring and the fine measurements of craftsmen.
In the modern market system the chi is exactly one third of a meter, which makes the fen one three hundredth of a meter, about 3.33 millimeters. It sits below the cun, and ten fen make one cun. Because ancient chi were far shorter than today's, ancient fen were correspondingly smaller. A separate Chinese fen also exists as a mass unit, and the same word was borrowed for fractions of other quantities, so context matters when the term appears.
1 fen (Chinese) = 0.003333333333 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).
