Yes, the conversion between cubic feet and gallons is well-established and can be proven through simple calculations based on known volume relationships.
The key conversion factors are:
- 1 gallon (U.S.) = 231 cubic inches
- 1 cubic foot = 1,728 cubic inches (since 12 inches × 12 inches × 12 inches = 1,728 cubic inches)
To convert cubic feet to U.S. gallons:
- Multiply the number of cubic feet by the number of cubic inches in one cubic foot (1,728).
- Divide the result by the number of cubic inches in one U.S. gallon (231).
So the formula is:
   Gallons=231Cubic Feet×1,728​
Example:
To convert 5 cubic feet to gallons:
  Gallons=2315×1,728​=2318,640​≈37.47 gallons
This is how the conversion works, and it’s a proven, reliable relationship based on standard units of measurement.
