accuracy=3The "shaku" (尺) is an archaic
Japanese unit oflength , approximately equal to the foot. As with other measurements, it was originally derived from nature: the average length between nodes onbamboo . Since1891 , the "shaku" has been defined to equal 10/33meter s (approximately 30.3 cm, or 11.93 inches), or 3.3 "shaku" to the meter. A single "shaku" is divided into 10 "sun" (寸).Another unit of length also called the "shaku" was used only for measuring cloth. This "shaku" measured 125/330 meters (approximately 37.9 cm, or 14.9 inches). When a distinction needed to be made between the two "shaku", the cloth unit was referred to as "kujirajaku" (whale "shaku", as the rulers for measuring cloth were made from whale whisker) and the other "shaku" was referred to as "kanejaku" (metal "shaku").
While
Japan ese law required official use of these units be discontinued onMarch 31 ,1966 , the "shaku" is still used in some fields in Japan, such as traditional carpentry. The "ken" and "jō" are larger than a "shaku": six "shaku" make up one "ken"; ten "shaku" make up one "jō". The "ken" is commonly the distance between pillars in traditional buildings such asBuddhist temple s and Shinto shrines.The
Shosoin in Nara has an ancient ivory one-"shaku" ruler.The
shakuhachi is a Japanesemusical instrument nominally measuring 1 "shaku" and eight ("hachi") "sun" in length.External links
