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

What Each Unit Is
Cubic Meters (m³) — the volume of a cube one metre on each side, equal to 1,000 litres. The SI derived unit of volume.
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.
A Sense of Scale
A cubic metre of water weighs 1 tonne- Domestic gas and water are billed per m³
- A coffee mug holds about 1.5 cups
- US recipes measure everything in cups
Precision
The factor 4226.75283773 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 m³ with the factor truncated at each decimal place:
| Decimals kept | Factor | 137 m³ becomes | Error |
|---|---|---|---|
| 0 | 4227 | 579,099 | 0.0058% |
| 1 | 4226.8 | 579,071.6 | 0.0011% |
| 2 | 4226.75 | 579,064.75 | — |
| 3 | 4226.753 | 579,065.16 | — |
| 4 | 4226.7528 | 579,065.13 | — |
The right number of significant figures is set by your input, not by the converter. If you measured cubic meters to three significant figures, the answer in cups is only good to three — writing more digits claims precision the measurement never had.
