Swedish units of measurement

Traditional Swedish units of measurement were standardized by law in 1665, prior to which they only existed as a number of related but differing local variants. The system was slightly revised in 1735. In 1855, a decimal reform was instituted that defined a new Swedish inch as Swedish foot (). Up to the middle of the 19th century, there was a law allowing the imposition of the death penalty for falsifying weights or measures. Sweden adopted the metric system in 1889, after a decision by the parliament in 1875 and a ten-year transition period from 1879. Only the Swedish mile, ''mil'', has been preserved, now measuring .
