The apothecary pound is an ancient Russian system for measuring mass. It was introduced in the 16th century under Ivan the Terrible and in the 17th century under Alexei Mikhailovich Tishaish (founder of the Romanov dynasty).
The apothecary pound system included a paper pound, a silk pound, a leather pound, a silver pound and a gold pound. Each pound had a certain weight, which was determined by the gold or silver content in it. The ratio of the mass of silver or gold to the mass of gold was the same.
The apothecary pound was used to determine the amount of medicines and other substances needed for treatment. It was very popular in Russia for many years, even though other weight measurement systems were introduced later.
Currently, the apothecary pound system is outdated and is not used in everyday life. However, it has its own history and cultural significance that can be interesting to explore.
