Li (Chinese) to Meters (li to m)
1 li (Chinese) equals 500 meters exactly.
How to convert li (Chinese) to meters
To convert li (Chinese) to meters, multiply the number of li (Chinese) by 500. This factor is exact. To go the other way, multiply meters by 0.002.
meters = li (Chinese) × 500
Example: 10 li (Chinese) = 5,000 meters.
About these units
Li (Chinese) (li)
The modern Chinese 'mile', set at exactly 500 meters. Imperial-era li varied widely, from about 323 m under the Tang to roughly 540-650 m under the Qing.
Field and earth are the two components of the character for li, an apt picture of a distance about the size of a village. Chinese travel writing, military records and poetry counted roads in li, and phrases such as the ten-thousand-li Great Wall or thousand-li horses turned it into a figure of speech for great distance. English writers sometimes call it a Chinese mile, though it is nearer a third of an English mile.
Its length followed the chi and the number of chi counted per li. Wikipedia lists about 358 m for the Western Zhou, about 416 m for the Han, about 323 m for the Tang and 537 to 645 m for the Qing, when some usage counted 1,800 chi per li instead of 1,500. Republican li ranged around 500 to 545 m. The figure used here is the modern value of exactly 500 m, which is 1,500 modern chi.
1 li (Chinese) = 500 meters (exactly).

Meter (m)
The SI base unit of length. Since 1983 it is defined as the distance light travels in a vacuum in 1/299,792,458 of a second.
Meter comes from the Greek metron, a measure. In 1791 the French National Assembly defined it as one ten-millionth of the distance from the equator to the North Pole along a great circle through Paris, after rejecting the length of a seconds pendulum because that length changes with local gravity. The surveyors Delambre and Méchain measured the meridian arc, and in 1799 a platinum bar known as the Mètre des Archives became the physical standard. NIST notes that this Earth-based meter turned out to be about 0.2 mm shorter than the true pole-to-equator fraction it was meant to represent.
The 1875 Treaty of the Meter created the CGPM and the BIPM to look after common standards, and in 1889 a platinum-iridium prototype bar took over; the original is still kept at the BIPM. In 1960 the meter was tied to 1,650,763.73 wavelengths of an orange-red krypton-86 line, and in 1983 to the speed of light, which made length a quantity derived from the time standard. The 2018 revision reworded that definition without changing the meter's size. NIST offers a handy yardstick for scale: a pace, meaning two steps, is roughly a meter or a yard.
The meter is the reference unit for length on this site.
