In physics, a characteristic length is an important dimension that defines the scale of a physical system. Often, such a length is used as an input to a formula in order to predict some characteristics of the system, and it is usually required by the construction of a dimensionless quantity, in the general framework of dimensional analysis and in particular applications such as fluid mechanics.
By 1472 the lira di grossi gave way to the ducat accounting unit, equal to 1 ⁄ 10 the lira di grossi or 24 grossi, and fixed at 6.2 lire or 124 soldi piccoli.

The last red złoty, the "insurgent ducat" of 1831. The red złoty was minted at 3.5 grams of gold. [4] There was also a silver złoty, worth 23.1 grams of silver. [4] In 1526 a monetary scale was introduced in which 1 złoty = 5 szóstaków (sixpences) = 10 trojaków (threepences) = 30 groszy = 90 szelągów (shillings) = 180 ternarów/trzeciaków = 540 denarów ().
Some of these coins reached colossal size, as much as sixteen normal thalers, exceeding a full pound (over 450 g) of silver and being over 12 cm (5 in) in diameter.
