Liters to Cubic Feet (L to ft³)

Common questions

How many cubic feet is 1 liter?

0.0353146667215 cubic feet, which is 1 divided by 28.316846592. Everything scales straight through, so 10 L is 0.353146667215 ft³, 100 L is 3.53146667215 ft³ and 1,000 L is 35.3146667215 ft³: the same digits with the point moved, because the whole conversion is a single division. The amounts asked about most often: 50 L is 1.76573333607 ft³, 200 L is 7.0629333443 ft³, 300 L is 10.5944000164 ft³ and 500 L is 17.6573333607 ft³. Type the liters into the From box and the answer appears without pressing anything, and Copy result copies the figure without the thousands separators so it pastes straight into a spreadsheet.

What is the formula for liters to cubic feet?

Cubic feet = liters / 28.316846592 for the international foot. Multiplying by the rounded reciprocal 0.0353146667215 only approximates that division and can change final rounding. The converter divides by the exact factor: 28.316846592 L gives exactly 1 ft³ and 566.33693184 L exactly 20 ft³. A shortened multiplier 0.0353 is about 0.04 percent low, with a deficit of about 0.015 ft³ at a supplied 1,000 L. Those are arithmetic differences; their practical effect depends on the measurement and task.

Why is 28.316846592 liters per cubic foot exact rather than approximate?

Because both units are defined rather than measured. The international foot has been exactly 0.3048 meters since the 1959 agreement on the yard and the pound, so a cubic foot is 0.3048 × 0.3048 × 0.3048 cubic meters, which is exactly 0.028316846592 m³. The liter has been exactly one cubic decimeter, a thousandth of a cubic meter, since 1964. A thousand times 0.028316846592 gives 28.316846592 liters in a cubic foot with no rounding at any step, and that is the number this converter carries.

Is the decimal exact, or is it rounded?

The factor is exact; the decimal going from liters to cubic feet is not. As a fraction, a cubic foot is 55,306,341/1,953,125 liters, so a liter is 1,953,125/55,306,341 of a cubic foot. The bottom of that fraction is 3³ × 127³, and a denominator carrying any prime other than 2 and 5 cannot produce a decimal that ends, so the factor 0.0353146667215 is a rounded repeating value; an input can still cancel the denominator. The page shows twelve significant digits and stops there, using decimal-rational arithmetic. Volumes that land on a whole multiple of 28.316846592 L come back exact: 56.633693184 L reads 2 ft³ and 283.16846592 L reads 10 ft³.

How do I convert cubic feet back to liters?

Multiply by 28.316846592. So 2 ft³ is 56.633693184 L, 5 ft³ is 141.58423296 L, 10 ft³ is 283.16846592 L and 20 ft³ is 566.33693184 L. That direction is the tidy one: multiplying by a decimal that terminates, so finite decimal inputs have terminating exact reverse values, though long answers still need display rounding. The Swap units button between the two boxes reverses the pair without a reload, and the number you typed stays where it is while the units change places.

Where do cubic feet get used instead of liters?

A specification may explicitly give appliance, tank, freight or storage volume in liters or cubic feet. Convert its stated unit rather than inferring a convention from the country or product: 300 L displays as 10.5944000164 ft³, 500 L as 17.6573333607 ft³, 200 L as 7.0629333443 ft³ and 20 ft³ as 566.33693184 L. One cubic meter, 1,000 L, displays as 35.3146667215 ft³. Conversion alone does not determine usable capacity, packing space or how the source measured the volume.

How is this different from converting liters to gallons or fluid ounces?

A cubic foot is a cube of a length, one foot along each edge, and it counts space: appliance interiors, bulk material, freight. The US gallon and the US fluid ounce are liquid measures defined off the cubic inch, since a US liquid gallon is exactly 231 cubic inches, and they answer the kitchen and the fuel pump. All of them sit in this one Volume category and convert cleanly between each other: a single cubic foot is 7.48051948052 US gallons, 957.506493506 US fluid ounces and 6.22883545904 imperial gallons. The list under the answer already carries the US gallon, quart, pint, cup, tablespoon, teaspoon and fluid ounce for whatever liter figure you typed, and the three imperial units and the cubic inch join it when you tick the switch marked Show 5 more.

How do I work out the liters or the cubic feet in the first place?

For a rectangular box, multiply length by width by height in the same unit: 2 m × 0.5 m × 0.4 m is exactly 0.4 m³, or 400 L, displaying as 14.1258666886 ft³. The linked Volume Calculator accepts cylinders and cones with perpendicular height, partly filled horizontal cylindrical tanks, and rectangular or oval pools with uniform or linearly varying depth. Its meter and centimeter modes list liters and cubic feet. These models do not cover arbitrary tanks or pools with steps, benches or freeform geometry.

Why does the page open on liters and cubic feet, and does it change my saved units?

This focused page opens on Liter and Cubic foot, while preserving the main converter’s saved unit pair. When storage is usable, a saved value and uncommon-unit preference can travel between pages. Its suffix must still match From. Valid deliberate scalar edits can save those fields after a short delay; invalid or incomplete drafts preserve the saved record. Unusable or conflicting records remain until you use Forget saved settings, which keeps the current conversion on screen.

Does anything I type here leave my browser?

Your input and converted values are calculated in the browser and are not uploaded by the converter. The definitions arrive with the page, so conversion needs no external data lookup and keeps working offline after the page has loaded. The core conversion needs no account. Copy result copies the displayed headline without digit-grouping commas; each visible conversion row has its own Copy button. Displayed and copied values round to twelve significant digits. If native copying fails, a complete selectable summary identifies the input, selected pair and conventions and includes every unit in the category, including uncommon units.
