To convert cubic feet to liters, multiply the volume in cubic feet by 28.316846592. This factor converts an imperial/U.S. customary cubic measure into the liter, a metric unit commonly used for liquid capacity, storage volume, tanks, appliances, shipping specifications and many other practical measurements.
Reverse formula: Cubic Feet = Liters ÷ 28.316846592
For example, if a container has a volume of 4 cubic feet, multiply 4 by 28.316846592. The result is 113.267386368 liters. For an everyday estimate, that can be rounded to 113.27 L.
A cubic foot is the volume of a cube measuring one foot on each side. The international foot is exactly 0.3048 meter, so the volume of a one-foot cube is 0.3048 × 0.3048 × 0.3048 cubic meter, which equals 0.028316846592 m³. Because one cubic meter contains exactly 1,000 liters, that becomes 28.316846592 L.
This is why volume conversion cannot use the ordinary linear feet-to-meters factor directly. Length is one-dimensional, area squares the linear factor, and volume cubes it. The same principle applies whenever you convert between cubic inches and cubic centimeters, cubic yards and cubic meters, or other three-dimensional measurements.

A cubic foot is a three-dimensional cube. The diagram shows the exact relationship between one ft³, cubic meters and liters.
A cubic foot is a unit of volume based on the foot. It represents the space inside a cube that is one foot long, one foot wide and one foot high. Cubic feet are common for appliance capacity, room volume, storage, shipping, construction materials and equipment specifications in the United States.
Because it is a cubic unit, the symbol should be written as ft³, not simply ft.
The liter is a metric volume unit accepted for use with SI and is exactly equal to one cubic decimeter. Liters are widely used for liquids, tanks, containers, engine displacement, food packaging and many international product specifications.
For larger metric volumes, 1,000 liters equal one cubic meter.
For the reverse conversion, divide the liter value by 28.316846592. The reciprocal factor is approximately 0.0353146667 cubic foot per liter.
Approximate shortcut: Cubic Feet = Liters × 0.0353146667
For example, 250 liters ÷ 28.316846592 ≈ 8.82866668 ft³. The second calculator above performs this reverse calculation automatically.
| Unit | Relationship | Common Use | Example |
|---|---|---|---|
| Cubic foot (ft³) | 1 ft³ = 28.316846592 L | Appliances, storage, building volume | 5 ft³ freezer |
| Liter (L) | 1 L = 0.001 m³ | Liquids, tanks, containers | 100 L tank |
| Cubic meter (m³) | 1 m³ = 1,000 L | Large metric volumes | 2 m³ storage |
| US gallon | 1 ft³ ≈ 7.48051948 US gal | Liquid capacity in the U.S. | 20 gal container |
| Cubic inch (in³) | 1 ft³ = 1,728 in³ | Small component volume | Engine or package volume |
If you have length, width and height rather than a ready-made cubic-foot value, first calculate the volume in cubic feet. When every dimension is measured in feet, multiply length × width × height. Then multiply the resulting cubic feet by 28.316846592 to obtain liters.
Example: a storage box measuring 2 ft × 1.5 ft × 1 ft has a volume of 3 ft³. That volume equals 84.950539776 liters.
The conversion factor itself can be used exactly, but real-world measurements may not be exact. If a container was measured only to the nearest inch or a product capacity is a nominal manufacturer value, adding many decimal places to the converted liter value does not make the original measurement more accurate.
For household capacity and general estimates, one or two decimal places are usually readable. For shipping, engineering, laboratory, manufacturing or technical documentation, retain enough digits to meet the project requirement and round only at the end of the calculation.
The calculator keeps useful precision internally and formats the displayed result for readability.
