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 Acre-Feet
An acre-foot (ac ft) = the volume covering 1 acre to 1 ft depth ≈ 1,233.5 m³ (325,851 US gal). Almost exclusively used in US water resource management. California's Lake Shasta: 4.55 million ac ft at capacity. A typical US household uses ~0.5-1 ac ft/year. Water rights on the Colorado and Sacramento rivers are traded in acre-feet. 1 ac ft ≈ 1,233.5 m³.
