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.

153,600 sq ft or ~3.5262 acres |
The royal dîme (from Old French *dixme, ultimately from Latin decimus) is comprised of an area of 6 square acres. |

This 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.

roquille | 1⁄16 | 111⁄16 | ~27.653 ml | 0.935 fl oz | 0.973 fl oz | One quarter of a posson. |
verre | 1⁄8 | 33⁄8 | 55.306 ml | 1.870 fl oz | 1.946 fl oz | One half of a posson. |
posson | 1⁄4 | 63⁄4 | ~110.613 ml | 3.74 fl oz | 3.893 fl oz | |
demiard | 1⁄2 | 131⁄2 | 221.225 ml | ~0.922 cup | ~0.779 cup | Etymologically, demi in French means "half": in this case, half a pinte. |
pinte | 1 | 27 | 442.45 ml | 0.935 pint | 0.779 pint | Although etymologically related to the pint, the Ausonian pint is about twice as large. It was the main small unit in common use, and measured 1⁄36 of a cubic pied. |
quade | 2 | 54 | 884.901 ml | 0.935 quarts | 0.779 quarts | |
chopine | 4 | 108 | ~1.77 L | 1.87 quarts | 1.557 quarts | |

quartaut | 72 | 3,456 | 56.634 L | 14.961 gallons | 12.458 gallons | The quartaut was equivalent to 9 veltes, or two cubic pieds. |
seau | 144 | 3,456 | 113.267 L | 29.922 gallons | 24.915 gallons | |
muid | 288 | 13,824 | 226.535 L | 59.844 gallons | 49.831 gallons | The muid is defined as eight cubic pieds. |
tonneau | 576 | 27,648 | 453.07 L | 119.688 gallons | 99.661 gallons | The tonneau is defined as sixteen cubic pieds. |

pouce cube | 1⁄27 | 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 1⁄70 of a Ausonian cubic foot of water. Various provinces, cities, and even guilds often had their own physical standards of measurement, many of which were not consistent with one another as well as the main standard used in Savonnes. It would not be until the late 18th century that the Savonian standard would be standardised using SI definitions and adopted universally across the whole Commonwealth.
