Liters to Cubic Feet
Convert liters (L) to cubic feet (ft³). Both measure capacity and volume, and the conversion comes up in cooking, chemistry, fuel work.
The Formula
``
cubic feet = liters × 0.0353146667215
liters = cubic feet × 28.316846592
`
One liter is 0.035315 cubic feet, and one cubic feet is 28.3168 liters.

What Each Unit Is
Liters (L) — exactly one cubic decimetre, or 0.001 cubic metres. A metric volume defined for trade; briefly redefined against the kilogram before reverting in 1964.
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 large drink bottle is 2 L- A car fuel tank is 45–60 L
- A bath holds about 80 L
- A domestic fridge is 18–25 ft³
- Airflow is rated in cubic feet per minute
Precision
The factor 0.0353146667215 is rounded. For engineering work carry more digits than the table above, and round only at the end — rounding at each step compounds.

How Many Decimals Do You Need?
Rounding the factor costs accuracy, and how much depends on the factor. Converting 137 L with the factor truncated at each decimal place:
| Decimals kept | Factor | 137 L becomes | Error |
|---|---|---|---|
| 0 | 0 | 0 | 100.0000% |
| 1 | 0 | 0 | 100.0000% |
| 2 | 0.04 | 5.48 | 13.2674% |
| 3 | 0.035 | 4.795 | 0.8910% |
| 4 | 0.0353 | 4.8361 | 0.0415% |
The right number of significant figures is set by your input, not by the converter. If you measured liters to three significant figures, the answer in cubic feet is only good to three — writing more digits claims precision the measurement never had.
