# Swedish units of measurement

In Sweden, a common system for weights and measures was introduced by law in 1665. Before that, there were a number of local variants. The system was slightly revised in 1735. In 1855, a decimal reform was instituted that defined a new Swedish inch as 1/10 foot. Up to the middle of the 19th century there was a law allowing for the imposition of the death penalty for falsifying weights or measures. Sweden adopted the metric system in 1889. Only the mil has been preserved, now measuring 10km, however.

## Length

• aln Forearm (cf. Ell) (pl. alnar). After 1863, 59.37 cm. Before that, from 1605, 59.38 cm as defined by king Carl IX of Sweden in Norrköping 1604 based on Rydaholmsalnen.
