A variety of other historical weights and measures have been employed throughout the nation's history.
The Danes started with a system of units based on a Greek pous ("foot") of 308.4 millimetres (1.012 ft) 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 52.5-foot-long (16.0 m) Hjortspring boat, which though dating to the early Iron Age exemplifies plank-built vessels of the late Bronze Age and the 82-foot-long (25 m) Nydam ship.
King Christian V of Denmark introduced an office to oversee weights and measures, a justervæsen.
This was first led by the royal mathematician Ole Rømer, who established a national system of weights and measures on May 1, 1683.
