What is a Dram Measurement?
The accuracy of measurement, especially in liquids is important. Even in the ancient periods, people have been using units of measurement to ensure absolute precision. Among the most common units used in ancient Greece which is still very useful in the measurements of today is the unit “dram”. In this scientific era, dram refers to a specific volume or mass measuring unit. These include fluid dram, fluidram, and fluidrachm. The equivalent of a dram in modern mass and volume measurement units vary depending on the type of system used in the conversion.

Although the exact history and origin of a dram unit is not known, many historians consider the measuring unit as an ancient Greek measuring method. During the 20th century, the apothecaries measurement system was developed in the US. In this system, a dram apothecary is equivalent to 60 grains. The medical field will still use dram units as a measurement. A teaspoon of fluid medication is one fluid dram unit. Dram
measurement is one of the few things that have survived through the many changes in the modern world. It is through these ancient measuring units that modern units were developed, and accuracy in the measurement of volume and mass has been achieved.
