About Cubic Foot and Cubic Millimeter
The cubic foot is exactly 28.316846592 liters. US appliances (refrigerators, freezers), natural gas billing, and HVAC airflow (CFM) are specified in cubic feet. The cubic millimeter is one thousandth of a cubic centimeter. It appears in precision engineering, 3D printing material estimates, and medical imaging measurements. One Cubic Foot equals 28316846.59 Cubic Millimeters (1 ft3 = 28316846.59 mm3). Cubic Foot is used in US refrigerator and freezer capacity and in natural gas billing. Cubic Millimeter is used in 3D printing material volumes.
Precision and Rounding:US and imperial volume units share names but differ in size (an imperial gallon is about 20% larger than a US gallon), so confirm which system a figure uses before converting. Kitchen work tolerates rounding to the nearest milliliter or quarter-teaspoon; fuel, chemistry, and brewing need three or more decimal places.
Conversion factors per NIST Special Publication 811 and the BIPM SI Brochure (9th edition) (reference).
