About the Cubic Feet to Liters
The Cubic Feet to Liters calculator converts a volume in cubic feet into liters and provides the reverse conversion relationship. With the default input of 1 cubic foot, it displays 28.316847 liters, alongside conversion rows for both directions.
- Value in cubic feet
- Enter the volume in cubic feet (ft³) to convert to liters; the default value is 1.
Formula and method
V_L = V_ft3 × 28.316846592; conversely, V_ft3 = V_L ÷ 28.316846592. Rounded to six decimal places: 1 cubic foot = 28.316847 liters and 1 liter = 0.035315 cubic feet.
- V_LVolume measured in liters (L).
- V_ft3Volume measured in cubic feet (ft³).
Multiply the entered cubic-foot volume by 28.316846592 to obtain liters, then round for display. For the default input of 1, the liters result is 28.316847. The reverse relationship is calculated by dividing a liter volume by the same factor; for 1 liter, the displayed equivalent is 0.035315 cubic feet.

How to use the Cubic Feet to Liters
- 1Find the Value in cubic feet input.
- 2Keep the default value of 1 to reproduce the worked example, or enter the cubic-foot volume you need to convert.
- 3Read the liters result; with the default input, it is 28.316847.
- 4Check the forward conversion row, which shows 1 cubic foot = 28.316847 liters.
- 5Use the reverse conversion row, 1 liter = 0.035315 cubic feet, as a reference; for a reverse calculation, divide the liter volume by the full conversion factor.
Reading your result
The 'liters' output is the entered volume expressed in liters: 28.316847 for the default input. The forward row, shown as '1 cubic feet = = 28.316847 liters', states the cubic-foot-to-liter relationship. The reverse row, shown as '1 liters = = 0.035315 cubic feet', states the equivalent of one liter, not a second conversion of the entered cubic-foot value. The duplicated equals signs are display formatting and do not change either relationship.
Limitations
The conversion assumes the international foot and uses the exact factor of 28.316846592 liters per cubic foot. Displayed values are rounded to six decimal places, so using the displayed reverse factor can introduce small rounding differences. Conversion does not improve the accuracy of the original measurement or account for changes in a substance's volume with temperature or pressure. This tool converts volume, not mass, and ordinary physical volumes should be nonnegative.
Common questions
Why does 1 cubic foot display as 28.316847 liters?+
The exact conversion is 28.316846592 liters per cubic foot. Rounding that value to six decimal places gives the displayed result of 28.316847 liters.
How do I convert liters back to cubic feet?+
Divide the volume in liters by 28.316846592. The reverse reference row shows that 1 liter is approximately 0.035315 cubic feet; the listed input field itself accepts cubic feet.
Why should I avoid multiplying by 0.035315 for high-precision reverse conversions?+
That displayed factor is rounded. Dividing by 28.316846592 retains more precision and reduces discrepancies when converting back and forth.
Can I enter a length measured in feet?+
No. The input must be a volume in cubic feet, not a length in feet. For a rectangular space, first multiply its length, width, and height measured in feet to obtain cubic feet.
Does the calculator save my information?+
Calculations run in your browser. While signed in, inputs and results are automatically recorded in account history; saving a result creates a separate saved record.
