Cups to Cubic Meters
Convert cups (cup) to cubic meters (m³). Both measure capacity and volume, and the conversion comes up in cooking, chemistry, fuel work.
The Formula
``
cubic meters = cups × 0.0002365882365
cups = cubic meters × 4226.75283773
`
One cup is 2.3659e-4 cubic meters, and one cubic meter is 4,226.75 cups.

What Each Unit Is
Cups (cup) — the US customary cup: exactly 240 millilitres in nutrition labelling, 236.588 mL legally. An American cooking measure standardised by Fannie Farmer in the 1890s.
Cubic Meters (m³) — the volume of a cube one metre on each side, equal to 1,000 litres. The SI derived unit of volume.
A Sense of Scale
A coffee mug holds about 1.5 cups- US recipes measure everything in cups
- A cubic metre of water weighs 1 tonne
- Domestic gas and water are billed per m³
Precision
The factor 0.0002365882365 is rounded. For engineering work carry more digits than the table above, and round only at the end — rounding at each step compounds.
Watch Out For
- A US cup is 237 mL, a metric cup 250 mL and a Japanese cup 200 mL. Baking by volume is why the same recipe fails in another country.

How Many Decimals Do You Need?
Rounding the factor costs accuracy, and how much depends on the factor. Converting 137 cup with the factor truncated at each decimal place:
| Decimals kept | Factor | 137 cup becomes | Error |
|---|---|---|---|
| 0 | 0 | 0 | 100.0000% |
| 1 | 0 | 0 | 100.0000% |
| 2 | 0 | 0 | 100.0000% |
| 3 | 0 | 0 | 100.0000% |
| 4 | 0.0002 | 0.0274 | 15.4649% |
The right number of significant figures is set by your input, not by the converter. If you measured cups to three significant figures, the answer in cubic meters is only good to three — writing more digits claims precision the measurement never had.
