About Cubic Foot and Cubic Meter
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 meter is the SI derived unit of volume — 1,000 liters. Construction (concrete, excavation), water utilities, and freight all bill by the cubic meter. One Cubic Foot equals 0.02831684659 Cubic Meter (1 ft3 = 0.02831684659 m3). Cubic Foot to Cubic Meter conversion comes up most often in US refrigerator and freezer capacity and in natural gas billing, typically when figures need restating for concrete and excavation quantities.
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).
