A variety of units of measurement were used in the various independent Italian states and Italian dependencies of foreign empires up to the unification of Italy in the 19th century. The units to measure length, volume, mass, etc., could differ widely between countries or between towns in a country (e.g. Rome and Ancona), but usually not between a country and its capital.
The Kingdom of Sardinia included the island of Sardinia and the continental areas of Piedmont (with the capital Turin) and Liguria (with Genoa). The Kingdom of Naples included the island of Sicily (with Palermo). The Kingdom of Lombardy–Venetia was part of the Austrian Empire, which also shared ruling family with Modena, Parma and Tuscany (capital Florence). The Papal States included the areas of Latium (with the capital Rome), Umbria, Romagna (with Bologna) and the Marches (with Ancona).

Milan adopted the metric system in 1803, during the Napoleonic Wars, albeit reusing names of older units.12 After the Congress of Vienna, the various Italian states reverted to their original systems of measurements.
In 1845 Sardinia passed legislation to introduce the metric system within five years. In 1859 Lombardy (but not Venetia) was annexed. In 1860 Parma, Modena, Tuscany, Umbria, Romagna and the Marches, and the Two Sicilies (Naples) were assimilated into Sardinia and under the Law 132 of 28 July 28, 1861 the metric system became the official system of measurement throughout the (this year) Italian kingdom.3 The last to be incorporated were Venetia (1866), and the rest of the Papal States (1870).
For historical Roman measurements, see Ancient Roman units of measurement. The following is a comprehensive list of units used prior to the adoption of the metric system, along with the local names assigned to metric-based units after the system change.
Over time, many traditional unit names were repurposed to denote metric-based units. This practice introduced an additional layer of complexity, making the transition to the metric system unnecessarily cumbersome. These units are marked with €. They are also placed after the traditional.
Length
Units varied from one province or city to another.2 In the north the atomo was the smallest unit.4
