In a ukase of 1818, the tsar redefined the vedro as the volume of 30 avoirdupois pounds of distilled water at a temperature of 13 1/3 degrees Réaumur.  The vedro was divided into 100 charka; comparing the chart above with that below will show the beginning of decimalization.

A ukase of 11 October 1835 defined the vedro as the volume occupied by 30 “livre russe” of distilled water at 13 1/3 degrees Réaumur. The same ukase defined the “livre russe” as the mass of 25.019 cubic (English) inches of distilled water at 13 1/3 degrees Réaumur, making the vedro, as the ukase notes, 750.57 cubic inches, which is 12.29964 liters. The ukase also defined the demi-vedro, krouchka and the polukrouchka.
