Fluid Ounces to Cubic Feet
Convert fluid ounces (fl oz) to cubic feet (ft³). Both measure capacity and volume, and the conversion comes up in cooking, chemistry, fuel work.
The Formula
``
cubic feet = fluid ounces × 0.00104437934028
fluid ounces = cubic feet × 957.506493506
`
One fluid ounce is 0.001044 cubic feet, and one cubic feet is 957.5065 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 Feet (ft³) — the volume of a cube one foot on each side, or 28.3168 litres. The imperial volume unit for freight, appliances and ventilation.
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 domestic fridge is 18–25 ft³
- Airflow is rated in cubic feet per minute
Precision
The factor 0.00104437934028 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 | 0.001 | 0.137 | 4.2494% |
| 4 | 0.001 | 0.137 | 4.2494% |
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 feet is only good to three — writing more digits claims precision the measurement never had.
