Conversion Formula
To convert cubic inches (ci) to gallons (gal), we divide the number of cubic inches by 231, because one US gallon is defined as exactly 231 cubic inches. This means that every 231 cubic inches contains 1 gallon.
So, the formula looks like this:
gal = ci ÷ 231
Example: For 6600 ci, the conversion is done by dividing 6600 by 231:
- 6600 ÷ 231 = 28.5714…
- The result is approximately 28.571 gallons.
This works because the volume units are proportional, and the conversion constant 231 comes from the definition of the US gallon.
Conversion Example
- Convert 5000 ci to gal:
- Divide 5000 by 231.
- 5000 ÷ 231 = 21.645 gal.
- So, 5000 cubic inches equals about 21.645 gallons.
- Convert 7500 ci to gal:
- 7500 ÷ 231 = 32.467 gal.
- Therefore, 7500 ci is approximately 32.467 gallons.
- Convert 1200 ci to gal:
- 1200 ÷ 231 = 5.1948 gal.
- This means 1200 cubic inches equals about 5.1948 gallons.
- Convert 300 ci to gal:
- 300 ÷ 231 = 1.2987 gal.
- So, 300 cubic inches is roughly 1.2987 gallons.

Conversion Definitions
ci (cubic inch): A cubic inch is a unit of volume in the Imperial and US customary systems. It represents a cube with each side measuring exactly one inch. It’s often used to measure the volume of small containers, engines displacement, and other compact spaces.
gal (gallon): A gallon, in the US customary system, is a unit of liquid capacity equal to 231 cubic inches. It’s commonly used to measure liquids like fuel, milk, or water. One gallon is approximately 3.785 liters in metric units.
Conversion FAQs
Can I convert cubic inches to gallons for any substance?
Yes, since cubic inches and gallons measure volume, the conversion applies regardless of the substance. However, volume doesn’t account for density or weight differences; so the actual mass varies depending on the material.
Why does the conversion use 231 cubic inches per gallon?
Because the US liquid gallon has been standardized as exactly 231 cubic inches. This fixed relationship allows straightforward volume conversions between these units.
Does this conversion work for UK gallons?
No, UK (imperial) gallons differ in size from US gallons. The UK gallon equals about 277.42 cubic inches, so the formula changes when converting ci to imperial gallons.
Are there rounding errors when converting ci to gal?
Yes, decimal results are often rounded to a few decimal places for simplicity. The exact mathematical division stays precise but displayed values may lose some precision.
How would I convert gallons back to cubic inches?
To convert gallons back to cubic inches, multiply the number of gallons by 231, reversing the division step in the formula.
