Cun. The cun 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. In time the lengths were standardized, although to different values in different jurisdictions.. In Hong Kong, using the traditional standard, it measures ~3.715 cm and is called a tsun.
