Imperial Decree on Standards, Measurements and Units (Premysloides Dynasty)

Imperial Decree on Standards, Measurements and Units
Imperial Decree on Standards, Measurements and Units, also known as "Arcadian-Valerian standardization reform", was imperial decree published in 1389 by Emperor Valerianus III, but reform itself was initiated by his father Arcadius the Restorer during Arcadius administrative reforms.

Main goal of this reform was optimalization and standardization of measurements and units in Empire to improve efficiency of bureaucracy, military, economy and commerce, judicial processes and government effectivity. Until this reform, various provinces used various units and measurements. Persians used shekel, pace or asparsa, while Romans used mile, sextarius or libra and Greeks solidus or litra etc. Just like Empire after expansion implemented currency unification with Hyperpyron, now Empire decided to take step in standardization.

In 1370, Arcadius the Restorer formed small commission of accountants, scientists, educators, technicians, merchants and military officers to form new standardized measures and units for Roman Empire.
