Conversion Formula
The formula to convert gallons to cubic is:
Cubic feet = Gallons × 0.133681
This works because one US gallon contains 231 cubic inches, and there are 1728 cubic inches in one cubic foot. Dividing 231 by 1728 gives approximately 0.133681 cubic feet per gallon.
Example:
Convert 25 gallons to cubic feet:
- Multiply 25 gallons by 0.133681 cubic feet/gallon
- 25 × 0.133681 = 3.342025 cubic feet
- The result rounds to 3.353 cubic feet
Conversion Example
- Convert 10 gallons to cubic feet:
- Multiply 10 by 0.133681
- 10 × 0.133681 = 1.33681 cubic feet
- So, 10 gallons equals 1.3368 cubic feet
- Convert 40 gallons to cubic feet:
- Multiply 40 by 0.133681
- 40 × 0.133681 = 5.34724 cubic feet
- Thus, 40 gallons equals 5.3472 cubic feet
- Convert 7.5 gallons to cubic feet:
- Multiply 7.5 by 0.133681
- 7.5 × 0.133681 = 1.0026 cubic feet
- Therefore, 7.5 gallons equals roughly 1.0026 cubic feet
- Convert 32 gallons to cubic feet:
- Multiply 32 by 0.133681
- 32 × 0.133681 = 4.2778 cubic feet
- Hence, 32 gallons equals 4.2778 cubic feet
- Convert 15 gallons to cubic feet:
- Multiply 15 by 0.133681
- 15 × 0.133681 = 2.0052 cubic feet
- So, 15 gallons equals 2.0052 cubic feet

Conversion Definitions
Gallons: Gallons are units of volume used primarily in the United States and a few other countries. One US gallon equals 128 fluid ounces or 3.785 liters. It measures the capacity to hold liquid, commonly used for fuel, water, and other fluids.
Cubic: Cubic units measure volume based on the cube shape, representing length × width × height in three dimensions. Cubic feet is a volume unit indicating a cube with edges of one foot. It’s used in architecture, storage, and liquid volume conversions.
Conversion FAQs
Can gallons be converted to cubic meters instead of cubic feet?
Yes, gallons can be converted to cubic meters by using a different conversion factor. One US gallon equals approximately 0.00378541 cubic meters. To convert gallons to cubic meters, multiply gallons by 0.00378541 instead of 0.133681 used for cubic feet.
Why do gallons not convert directly to cubic inches?
Gallons and cubic inches measure volume but use different bases. One gallon contains 231 cubic inches, so conversion involves multiplying gallons by 231. Direct conversion between gallons and cubic inches requires knowing this fixed relation since gallons are larger volume units.
Is there a difference between US gallons and UK gallons in conversions?
Yes, US gallons and UK (imperial) gallons differ in size. One UK gallon equals 1.20095 US gallons. Therefore, converting UK gallons to cubic feet uses a different factor, approximately 0.160544 cubic feet per UK gallon, compared to 0.133681 for US gallons.
How accurate is the gallon to cubic feet conversion?
The conversion is very accurate because it is based on fixed measurement standards. However, rounding numbers during calculation may introduce slight differences. For practical uses, using four decimal places like 0.1337 is sufficient for most volume conversions.
Do these conversions apply to both liquid and dry gallons?
No, liquid gallons and dry gallons differ. The US liquid gallon is most common, but dry gallons are used for dry volume measurements and are about 4.4049 liters, different from 3.785 liters for liquid gallons. Conversion factors will vary based on which gallon type is used.
