Fluid Ounces to Cubic Meters
Convert fluid ounces (fl oz) to cubic meters (m³). Both measure capacity and volume, and the conversion comes up in cooking, chemistry, fuel work.
The Formula
``
cubic meters = fluid ounces × 0.0000295735295625
fluid ounces = cubic meters × 33814.0227018
`
One fluid ounce is 2.9574e-5 cubic meters, and one cubic meter is 33,814.02 fluid ounces.

What Each Unit Is
Fluid Ounces (fl oz) — the US fluid ounce: exactly 29.5735295625 millilitres. One sixteenth of a US pint, descended from the wine gallon.
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 shot is 1.5 fl oz- A soda can is 12 fl oz
- A US coffee cup is 8 fl oz
- A cubic metre of water weighs 1 tonne
- Domestic gas and water are billed per m³
Precision
The factor 0.0000295735295625 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 UK fluid ounce is 28.41 mL — close enough to confuse, far enough to ruin a cocktail.

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