About Cubic Feet
A cubic foot (ft³) is the volume of a cube with sides of one foot (30.48 cm), equal to approximately 28.317 liters. It is widely used in US construction, HVAC engineering, natural gas distribution, and real estate. Natural gas consumption is billed in cubic feet (Ccf = 100 ft³, Mcf = 1,000 ft³); refrigerator, oven, and storage compartment capacity are rated in cubic feet; and concrete or soil orders are quoted in cubic yards or cubic feet. One cubic foot of water weighs approximately 62.4 pounds. Air conditioning units are sized in BTU per hour for room volumes measured in cubic feet.
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.
