Conversion Formula
The formula to convert gallons to cubic feet is:
Cubic feet = Gallons × 0.133681
This conversion works because one gallon is defined as 0.133681 cubic feet. When you multiply the volume in gallons by this factor, you get the volume in cubic feet. The factor comes from the relationship between the gallon unit and the cubic foot unit in the U.S. customary system.
For example, converting 2 gallons:
- Start with 2 gallons
- Multiply by 0.133681 cubic feet per gallon:
- 2 × 0.133681 = 0.267362 cubic feet
- The result rounds to 0.2671 cubic feet
Conversion Example
Let’s convert 5 gallons to cubic feet step-by-step:
- Identify the input: 5 gallons
- Use the conversion factor: 1 gallon = 0.133681 cubic feet
- Multiply: 5 × 0.133681 = 0.668405 cubic feet
- Result: 5 gallons equals about 0.6684 cubic feet
Another example, converting 10 gallons:
- Start with 10 gallons
- Multiply by 0.133681:
- 10 × 0.133681 = 1.33681 cubic feet
- Answer: 10 gallons is 1.3368 cubic feet
One more example, 0.5 gallons:
- 0.5 gallons
- Multiply by 0.133681:
- 0.5 × 0.133681 = 0.0668405 cubic feet
- Approximately 0.0668 cubic feet

Conversion Definitions
Gallons: Gallons is a unit of volume mostly used in the United States and a few other countries. It measures liquid capacity, and one gallon equals 128 fluid ounces or about 3.785 liters. Gallons can refer to US liquid gallons or imperial gallons, but US liquid gallons are more common in conversions.
Cubic: Cubic refers to a unit of volume measured in cubic units, such as cubic feet, cubic meters, or cubic inches. It represents the space occupied by a three-dimensional object. Cubic units are derived by multiplying length, width, and height in the same unit system to find volume.
Conversion FAQs
Why does converting gallons to cubic feet use the factor 0.133681?
The factor 0.133681 comes from the exact volume of one US gallon expressed in cubic feet. One US gallon is defined as 231 cubic inches. Since one cubic foot equals 1728 cubic inches, dividing 231 by 1728 gives 0.133681 cubic feet per gallon.
Can I convert gallons to other cubic units using this method?
You can convert gallons to other cubic units, but the conversion factor will change. For example, converting gallons to cubic meters requires a different factor, about 0.003785. The key is always to know the volume equivalence between the units involved before multiplying.
Are gallons and cubic feet used in the same industries?
Gallons are popular in liquid volume measurement, especially in fuel and water industries, while cubic feet are common in construction, storage, and air volume measurements. Sometimes both units appear together, requiring conversion for clarity or calculation.
Does temperature or pressure affect gallon to cubic feet conversion?
Temperature and pressure can affect the volume of gases, but for liquids, the change is minimal under normal conditions. The gallon to cubic feet conversion assumes standard temperature and pressure, so if volume changes due to environment, adjustments might be necessary.
Is it possible to convert negative gallon values to cubic feet?
Mathematically, negative values can be converted using the same factor, resulting in negative cubic feet. While negative volume has no physical meaning, in some calculations or simulations negative values represent deficits or direction in flow.
