How to Convert Litres to Cubic feet (L to ft³)
Volume conversions help with baking from American recipes, comparing petrol prices quoted per gallon abroad with pump prices per litre here, and reading PUB water bills in cubic metres. This guide shows how to convert litres into cubic feet by hand, with examples and a quick-reference table.
The conversion
To convert litres to cubic feet, multiply the value by 0.0353146667. To go the other way, divide by the same number (or multiply by 28.3168466). For a quick estimate, multiply by about 0.035.
Cubic feet = litres × 0.0353146667
Worked examples
- 3 L = 0.105944 ft³
- 12.5 L = 0.441433 ft³
- 75 L = 2.6486 ft³

Common questions
Is L to ft³ exact?
The factors used here are the internationally defined values where they exist; results are rounded for display only.
How do I convert back?
Divide by the same factor you multiplied by, or reverse the formula above.
Mistakes to avoid
Forgetting squared and cubed units
Area and volume factors are the length factor squared or cubed, so 1 m² is about 10.76 sq ft, not 3.28.
Rounding the factor too early
Using 3 instead of 3.28 for feet per metre introduces an error of almost 9% before you have started.
Mixing similar-sounding units
US and imperial gallons, pints and tons are different sizes, and decimal kilobytes differ from binary kibibytes.
Background
A conversion table is handy for common values, but a calculator is faster and avoids interpolation errors for anything in between.
Many conversion factors are exact by definition. The inch has been defined as exactly 2.54 centimetres since 1959, and the pound as exactly 0.45359237 kilograms, so conversions involving them can be as precise as you need.
Writing the units next to every number while you work is the simplest way to avoid mistakes. If the units do not cancel to leave the one you want, the calculation is set up wrongly.
