The History and Significance of the Drachm Unit of Weight

Drachms are an old unit of weight or mass, which were used in various countries before the adoption of the metric system. The word "drachm" comes from the Greek word "drachma," which means "handful" or "weight."

In ancient Greece, a drachm was equal to about 3.4 grams, and it was used as a unit of weight for precious metals like gold and silver. Later, the term was adopted by the Romans and other European countries, where it was used to measure the weight of various substances, including grains, gems, and medicines.

In the United States, the drachm was sometimes used in the 19th century as a unit of weight for drugs and other substances, but it was eventually replaced by the metric system. Today, the term "drachm" is mostly used in historical or scientific contexts to refer to ancient units of weight.
