Convert US cups to Cubic metres
1 US cup is 0.0002366 m³. One US cup is exactly 0.0002365882365 cubic metres.
One US cup is 2.3659 × 10^-4 cubic metres. To convert US cups to cubic metres, multiply by 2.3659 × 10^-4; to go the other way, divide by 2.3659 × 10^-4 or multiply by 4226.7528. 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. Eight US fluid ounces, about 236.6 ml.

What is a US cup?
Eight US fluid ounces, about 236.6 ml. The "legal" cup on nutrition labels is a rounded 240 ml.
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.
How many cubic metres are in a US cup?
One US cup is 2.3659 × 10^-4 cubic metres. Going the other way, one cubic metre is 4226.7528 US cups. 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.
