›› Definition: Chinese foot

The chi (Chinese: 尺; pinyin: chǐ, Wade-Giles: chih) or shaku (Japanese: 尺) is a traditional Chinese and Japanese unit of length, approximately equal to the foot. As with other measurements, it was originally derived from nature: the average length between nodes on bamboo. In both countries the same character is used to write the name for both units. Although of common origin, the current standard value of the two units is slightly different in the two countries.

In both countries, the chi or shaku is divided into 10 smaller units, known as 寸 (cun in China, or sun in Japan). 10 chi or shaku are equal to a 丈 (zhang in Chinese, or jō in Japanese).


›› Definition: Astronomical unit

The astronomical unit (AU or au or a.u. or sometimes ua) is a unit of length. It is approximately equal to the mean distance between the Earth and Sun. The currently accepted value of the AU is 149 597 870 691 ± 30 metres (about 150 million kilometres or 93 million miles).

The symbol "ua" is recommended by the Bureau International des Poids et Mesures, but in the United States and other anglophone countries the reverse usage is more common. The International Astronomical Union recommends "au" and international standard ISO 31-1 uses "AU".
