The Danes started with a system based on a Greek pous of 308.4 mm which they picked up through trade in the late bronze age early iron age. Some early standards of measure can be recovered from measured drawings made of the 52 1/2 foot long Hjortspring boat which though dating to the early iron age exemplifies plank built vessels of the late bronze age and the 82 ft long Nydam ship. Thwarts are typically spaced about 3 fod apart. From May 1, 1683, King Christian V of Denmark introduced an office to oversee weights and measures, a justervæsen, first led by Ole Rømer. The definition of the alen was set to 2 Rhine feet. Rømer later discovered that differing standards for the Rhine foot existed, and in 1698 an iron Copenhagen standard was made. A pendulum definition for the foot was first suggested by Rømer, introduced in 1820, and changed in 1835. The metric system was introduced in 1907.

Length

• mil – Danish mile. Towards the end of the 17th century, Ole Rømer, Mercator and other contemporaries of the great Dutch cartographer Thisus began following Claudius Ptolomy in connecting the mile to the great circle of the earth, and Roemer defined it as 12,000 alen. This definition was adopted in 1816 as the Prussian Meile. The coordinated definition from 1835 was 7.532 km. Earlier, there were many variants, the most commonplace the Sjællandsk miil of 17,600 alen or 11.13 km.
