Convert Cubic metres to Cubic feet
1 cubic metre is 35.31 ft³. One cubic metre is exactly 35.3146667215 cubic feet.
One cubic metre is 35.314667 cubic feet. To convert cubic metres to cubic feet, multiply by 35.314667; to go the other way, divide by 35.314667 or multiply by 0.028316847. The relation is exact but the figure is not: it is a rounding of a number that does not terminate, and it follows from NIST Handbook 130. Exactly a thousand litres, by the definition of the litre.

Cube the linear factor, not the volume you expect
A meter is 3.28 feet, so a cubic meter is 3.28³ = 35.31 cubic feet. The instinct to reach for the linear ratio is why volume estimates come out an order of magnitude short. In practice: a cubic yard of concrete is 27 ft³ and takes 60 sixty-pound bags or 45 eighty-pound ones, and a cubic meter is 1.31 cubic yards, so ordering "a yard" in Canada and "a meter" in the US are not the same order.

What is a cubic metre?
Exactly a thousand litres, by the definition of the litre. The SI unit of volume, and how the rest of the world orders concrete.
What is a cubic foot?
Exactly 28.316846592 litres, or 7.48 US gallons. The working unit of natural gas billing, air flow and refrigerator capacity in the US.
How many cubic feet are in a cubic metre?
One cubic metre is 35.314667 cubic feet. Going the other way, one cubic foot is 0.028316847 cubic metres. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.
