The cun (Chinese: 寸; pinyin: cùn; Wade-Giles: ts'un) is a traditional Chinese unit of length. Its traditional measure is the width of a person's thumb at the knuckle, whereas the width of the two forefingers denotes 1.5 cun and the width of all fingers side-by-side is three cuns. In this sense it continues to be used to chart acupuncture points on the human body in various uses of traditional Chinese medicine.
The cun was part of a larger system, and represented one-tenth of a chi (Chinese foot). In time the lengths were standardized, and in Hong Kong, using the traditional standard, it measures ~3.715 cm (~1.463 in). In the twentieth century in the Republic of China, the lengths were standardized to fit with the metric system, and in current usage in China and Taiwan it measures 31⁄3 cm (~1.312 in).
