Convert from stick to ri [Japan]

Unit Definition (stick)
A stick, when used as a unit, is usually two inches, i.e. 5.08 cm (for the international inch). It was once used in the English tailoring business, but has since fallen out of use completely.

Unit Definition (ri [Japan])
The ri is a traditional Japanese unit of distance, sometimes called the Japanese league because it is of similar length to the European league. The ri equals 2160 ken or 12 960 shaku (the shaku being the Japanese equivalent of the foot). This is about 3927 meters or 2.44 statute miles.
