As in thecase of the Danes, theNorwegians' earliest standards of measure can be derived from theirship burials. The 60-Norwegian-feet-longKvalsund ship (18.8 m; 61.8 ft) was built ca. 700 AD and differs from theDanish boats less than it does from theOseberg,Gokstad andTune ships which all date from ca. 800 AD. Thwarts are typically spaced about 3 Norwegian feet (0.94 m; 3.1 ft) apart.[1]

Themetric system wasintroduced in Norway in 1875, with Norway being one of the original signatories of themeter convention.
