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).
A light day (also written light-day) is a unit of length. It is defined as the distance light travels in an absolute vacuum in one day (of 86,400 seconds) or 25,902,068,371,200 metres (~26 Tm).
Note that this value is exact, since the metre is actually defined in terms of the speed of light. The light day isn't very frequently used at all since there are few astronomical objects or distances of that magnitude; the Oort cloud, for example, is thought to extend between 290 and 580 light-days out from the Sun.
