One Cubic Foot equals 0.02831684659 Cubic Meters (1 ft3 = 0.02831684659 m3). Cubic Foot is used in US refrigerator and freezer capacity and in natural gas billing. Cubic Meter is used in 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).
