Conversion Formula
The formula to convert gallons to cubic is:
Cubic feet = Gallons × 0.1336805556
This works because 1 US gallon equals exactly 231 cubic inches. We know that 1 cubic foot equals 1728 cubic inches, so dividing 231 by 1728 gives the conversion factor of about 0.13368.
For example, converting 5 gallons:
- Multiply 5 (gallons) by 0.1336805556
- 5 × 0.1336805556 = 0.668402778
- Rounded to four decimals: 0.6684 cubic feet
Therefore, 5 gallons equals approximately 0.6684 cubic feet.
Conversion Example
- Convert 12 gallons to cubic:
- Multiply 12 by 0.1336805556
- 12 × 0.1336805556 = 1.604166667
- Result is about 1.6042 cubic feet
- Convert 3.5 gallons to cubic:
- 3.5 × 0.1336805556 = 0.4678819446
- Rounded result: 0.4679 cubic feet
- Convert 20 gallons to cubic:
- 20 × 0.1336805556 = 2.673611112
- Rounded to 2.6736 cubic feet
- Convert 0 gallons to cubic:
- 0 × 0.1336805556 = 0
- So 0 gallons equals 0 cubic feet

Conversion Definitions
Gallons: Gallons is a unit of volume used primarily in the United States and some other countries, representing liquid capacity. One US gallon equals exactly 231 cubic inches or approximately 3.785 liters. It is commonly used for measuring liquids like fuel, water, and milk.
Cubic: Cubic refers to cubic feet, a unit of volume used in the imperial and US customary systems. One cubic foot is the volume of a cube with edges one foot long, equal to 1728 cubic inches or about 28.3168 liters. It measures three-dimensional spaces or containers.
Conversion FAQs
Why is the conversion factor between gallons and cubic feet not a whole number?
The conversion factor arises from the exact volume of a gallon in cubic inches (231) divided by the number of cubic inches in a cubic foot (1728). Because these values are fixed but not multiples of each other, the factor is a decimal, about 0.13368.
Can I use this conversion for UK gallons?
No, UK gallons differ in size than US gallons. One UK gallon equals 4.54609 liters, which is larger than the US gallon. This conversion factor is only valid for US gallons to cubic feet.
Why might the result sometimes differ slightly between calculators?
Rounding errors or differences in decimal precision used in calculators cause small discrepancies. Some tools might use rounded conversion factors or fewer decimal places, causing slight differences in output.
Is the conversion valid for both liquids and solids?
The conversion strictly relates volume units, so it applies regardless of the substance’s state. However, density and material properties are not considered, so mass or weight conversions require additional information.
How to convert gallons to other cubic units?
First, convert gallons to cubic feet using the factor 0.13368. Then, convert cubic feet to the desired unit, like cubic meters or cubic inches, using their respective conversion factors.
