About Cubic Millimeters
A cubic millimeter (mm³) is the volume of a cube with sides of one millimeter - equal to one millionth of a liter (0.001 mL). Despite its tiny size, the cubic millimeter is an essential unit in engineering and science. In medicine, red blood cell counts are reported per cubic millimeter of blood (a healthy adult has roughly 5 million red blood cells per mm³). In 3D printing and CNC machining, material volumes and tolerances are routinely specified in mm³. A single raindrop is roughly 50 mm³, and a grain of table salt approximately 0.1 mm³.
About Fluid Drams
A fluid dram (fl dr, also 'drachm') = 1/8 fl oz ≈ 3.697 mL. Used by apothecaries for precise medicinal compounding; a fluid dram divided into 60 minims. Largely superseded by millilitres but still appears in traditional compounding recipes, older US pharmacopeias, and historical medical literature. 1 fl dr ≈ 3.697 mL.
