The traditional Polish units of measurement included two uniform yet distinct systems of weights and measures, as well as a number of related systems borrowed from neighbouring states. The first attempt at standardisation came with the introduction of the Old Polish measurement [system], also dubbed the Warsaw system, introduced by a royal decree of December 6, 1764. The system was later replaced by the New Polish measurement [system] introduced on January 1, 1819.

The traditional Polish systems of weights and measures were later replaced with those of surrounding nations (due to the Partitions of Poland), only to be replaced with metric system by the end of the 19th century (between 1872 and 1876).
