# Austrian units of measurement

Austrian units of measurement were used in that country until the adoption of the metric system.

## History

In 1756, the ruling Arch duchess of Austria, Maria Theresa, ordered that the Vienna fathom, as well as its multiples and fractions, should be the state-defined measure of length in the Arch duchy of Austria and the Kingdom of Hungary. The Vienna cubit, that is 134 of the Roman cubit (cubit's or elbow), was also used as a measure of length.

The law should also have applied to the Lands of the Bohemian Crown, of which Maria Theresa was the Queen. However, the traditional Roman foot remained in common use in Prague.

When the metric system was introduced by law on 23 July 1871 (which became obligatory on 1 January 1876), the length of the fathom (Kl after) was established as exactly 1.89648384 m.
