Convert Liters to Cubic Feet - Volume Converter
This converter translates a volume value in liters (L) to cubic feet (ft³) using the fixed mathematical relationship between the two units. Use it for quick engineering checks, lab notes, inventory sizing, or when preparing documentation that mixes metric and imperial volumes.
The output is intended as a numerical conversion only. For regulated measurements, calibration traceability, or legal reporting follow the applicable standards and record measurement uncertainty as described below.

Quick reference table
| Liter | Cubic Foot |
|---|---|
| 1 L | 0.0353 ft³ |
| 5 L | 0.1766 ft³ |
| 10 L | 0.3531 ft³ |
| 25 L | 0.8829 ft³ |
| 50 L | 1.7657 ft³ |
| 100 L | 3.5315 ft³ |
Methodology
The tool applies a constant conversion factor that maps one liter to the exact defined equivalent in cubic feet. The conversion factor is based on the base SI definition of the liter and the internationally accepted length-to-volume relationships.
Accuracy guidance: for general-purpose conversions use 6–9 significant digits. For regulatory, safety, or contractual work, consult NIST and ISO documents and include instrument uncertainty and calibration records as required by the relevant authority.
Key takeaways
Use the provided factor (1 L = 0.035314666721489 ft³) for direct, repeatable conversions.
For compliance or safety-critical reporting include instrument uncertainty and reference the applicable standards (NIST, ISO, IEEE, OSHA) as required by the regulating body.
Worked examples
Example 1: 1 L → 1 × 0.035314666721489 = 0.0353146667 ft³ (useful for high-precision lab notes).
Example 2: 1000 L → 1000 × 0.035314666721489 = 35.3146667215 ft³ (round to 35.3147 ft³ for four decimal places).
Example 3: 250 L → 250 × 0.035314666721489 = 8.8286666804 ft³ (round to 8.829 ft³ for three decimals).
F.A.Q.
How many liters are in one cubic foot?
One cubic foot equals 28.316846592 liters.
How many significant digits should I keep?
For everyday use 3–4 significant digits are sufficient. For engineering or scientific work use 6–9 significant digits and always state measurement uncertainty when required by standards or contracts.
Is this conversion exact?
The conversion uses the defined constants for SI and imperial units, but practical measurements have uncertainty. The mathematical factor is fixed; the measured volume may vary due to instrument error, temperature, pressure, or sampling method.
When should I consider calibration and traceability?
When conversions support legal reporting, safety calculations, batch mixing, or contractual obligations, ensure measuring devices are calibrated, traceable to national standards, and that uncertainty is documented in line with NIST and ISO guidance.
Do I need to adjust for temperature or pressure?
Liquids are typically affected by temperature; volumes of gases are affected by both temperature and pressure. If your application is temperature- or pressure-sensitive, apply the appropriate thermophysical corrections before or after unit conversion.

Semantic versioning
- MAJOR: Calculation outputs can change for the same inputs (formula, rounding policy, assumptions).
- MINOR: New features or fields that do not change existing outputs for the same inputs.
- PATCH: Bug fixes, copy edits, or accessibility changes that do not change intended outputs except for previously incorrect cases.
Review protocol
- Verify formulas and unit definitions against primary standards or datasets.
- Run golden-case regression suite and edge-case suite.
- Record reviewer sign-off with credentials and scope.
- Document assumptions, limitations, and jurisdiction applicability.
Assumptions & limitations
- Uses exact unit definitions from the Fidamen conversion library.
- Internal calculations use double precision; display rounding follows the unit's configured decimal places.
- Not a substitute for calibrated instruments in regulated contexts.
- Jurisdiction-specific rules may require official guidance.
