Gallon to Ounce Conversion Formula
The main conversion formula is:
Gallons to Fluid Ounces
Fluid Ounces = Gallons × 128
Because:
1 Gallon = 128 Fluid Ounces
Example:
Convert 5 gallons into ounces.
Formula:
Fluid Ounces = 5 × 128
Result:
5 gallons = 640 fluid ounces
Fluid Ounces to Gallons Formula
To convert fluid ounces into gallons, use:
Gallons = Fluid Ounces ÷ 128
Because one gallon contains 128 fluid ounces.
Example:
Convert 256 fluid ounces into gallons.
Formula:
Gallons = 256 ÷ 128
Result:
256 fluid ounces = 2 gallons
