Ausonian customary units of measurement (French: unités de mesure ausoniennes) are a system of measurements commonly used in Ausonia. Inherited from the ?? system, which in turn was derived from the ancient Valessian measures, the system was later redefined in the 17th century, during the reign of Charles X, which became the standard of the Kingdom replacing local variations. It would later spread to the rest of Ausonia following the War of Unification, and has since been continuously updated and refined over the centuries to the present day. Today, Ausonia is one of the few countries (and the only one in Adria) that have not adopted the metric system as their official system of weights and measures.

Ausonians primarily use Ausonian units in commercial activities, as well as for personal and social use. In science, medicine, many sectors of industry, and some of government and military, metric units are used. For newer units of measure where there is no traditional customary unit, international units are used, sometimes mixed with customary units, such as electrical resistance of wire expressed in ohms (SI) per tour.

The royal dîme (from Old French *dixme, ultimately from Latin decimus) is typically used in the former Kingdom, and is comprised of an area of 6 square acres.

~4.7016 acres
Compared to the royal dîme, this is typically used in the Old Confederacy, and is comprised of an area of 8 square acres.

Volume

As in many ancient systems of measurement, the Ausonian distinguishes between dry and liquid measurements of capacity. Note that the quartier appears in both lists with vastly differing values.

pouce cube 127 1 16.387 ml 0.554 fl oz ~0.577 fl oz This is the Ausonian cubic inch.
pied cube 64 1,728 ~28.317 L 7.48 gallons ~6.229 gallons This is the Ausonian cubic foot. In ancient times, a cubic foot was also known as an amphora when measuring liquid volume.

Dry measures

Weight/mass

Two systems of weight are in use in Ausonia, an ordinary one in common use, and an apothecaries' system.

General System

Traditionally, the Ausonian pound (livre) was defined as the mass of exactly ​​170 of a Ausonian cubic foot of water. In the 18th century, these were redefined around the ...
