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 Firkins
A firkin (fir) ≈ 34.07 L (9 US gallons) - the most common cask for British real-ale delivery (9 imperial gallons = 40.91 L). A busy pub cellar cycles through several firkins per week. Craft breweries stage 'firkin tappings' of limited experimental ales. The name comes from Middle Dutch 'vierdekijn' (little fourth), as a firkin was one quarter of a barrel. 1 fir = 9 US gal ≈ 34.07 L.
