Unit Convertor: 
convert between shaku, sun, and bu, the metric system, and inches

It seems today no self-respecting website is complete without at least one Java script. To avoid all suspicion of computer illiteracy, this impressively sophisticated and exciting program performs an extremely powerful, fast and accurate conversion between shaku, sun and bu, cm and even inch (you know, 3 barleycorns).

shaku - sun - bu

Shaku, sun, bu is a traditional Japanese length measure, a shaku being close to a foot. One shaku equals ten sun, and one sun equals ten bu. One bu is equivalent to 3.03022 mm, unless when used for measuring cloth, when it corresponds to 3.787 mm, or for indicating footwear sizes, in which case it corresponds to only 2.4 mm. Today the shaku-sun-bu unit system is used almost exclusively for atavistic measurements such as the length of swords and other traditional weapons (as in the roku-shaku bo for example).
