In acupuncture clinical, it is necessary to select the correct acupoints. The position of the acupuncture point is defined by the distance and direction from the bone protrusion or the like as an index, and the unit is the traditional Chinese system of weights and length measures, “shakkanhou”. “Sun”= 寸 is length unit in shakkanhou. In the text that is used in the acupuncture therapist’s training course, defined as 1-“sun”= 3 cm. Considering individual differences in physique, it is impossible to search for the acupuncture points of all people by 1-“sun”= 3 cm, and in clinical practice, adjust according to each person’s physique for convenience. Even so, 1-“sun” = 3 cm is slightly too long for an average physique patient. In metric system, there is a standard that １ m is equal to the distance of vacuum space where light travels in 1/299,792,458 seconds （about 1/300 million seconds）. On the other hands, the length of the 1- “sun” has been historically changing.
In this survey we review and reports the 1- “sun” reference value based on actual measurements of the human body.
