From May 1, 1683, King [[Christian V of Denmark]] introduced an office to oversee weights and measures, a ''justervæsen'', to be 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.
