The Pskovian Weights and Measure Act of 1432 refers to a 1432 law in which the Pskovian Veche decided to standardize the weights and measures used throughout the Pskov Republic for trade purposes, and make them in relation to the rest of Europe (an example of this being the Pskovian zolotnik being equivalent to three=halves of the gold in the Venetian Ducat, a currency widely used by traders due to its reliability). This act was met by protest at first by the Muscovites, which had their own ruble, but for the time being it is unknown what the Muscovite ruble actually is so it is unknown how profound the protests are ... in any case, the sentence before shall be updated with new information. with some exceptions, most units go by multiples of five for smaller, and ten for larger units (in terms of the one before it).

Some Equivalencies

To the accuracy of 0.04 grams, 14 Uncia, 1 Dolia ► 1 troy Pound.

However, due to the extremely small nature of the Dolia, to most people

14 Pskov Ounces ► 1 troy Pound

1 Pskov Ounce ► 14/12 Troy Ounces

These equivalencies are accurate to a degree, even to some modern standards, the difference is not noticeable, let alone to the ... dodgey standards of anything pre-industrial in terms of measurements.
