How many milliliters are in 1 dram?

One dram is equivalent to 5 milliliters. This measure comes from the apothecary system, which is a traditional system of weights and measures that was historically used by pharmacists to dispense medications. The dram is still encountered in pharmacy practice, particularly when converting older prescriptions or formulations that utilize this system.

Understanding this conversion is crucial for accuracy in medication dosing and compounding, especially when dealing with formulations that may specify amounts in drams. It ensures that healthcare professionals can correctly interpret and prepare medications for patient use based on standardized measurements.
