For example:

Buying Liquid Products
Many products, from milk and juice to cleaning supplies, are sold in ounces and gallons. Understanding the conversion can help you make informed purchasing decisions.
How to Convert Ounces to Gallons
If you have a specific number of ounces and need to convert it to gallons, use this simple formula:
Ounces ÷ 128 = Gallons
For example:
- 64 ounces ÷ 128 = 0.5 gallons (half a gallon)
- 32 ounces ÷ 128 = 0.25 gallons (one-fourth of a gallon)
- 16 ounces ÷ 128 = 0.125 gallons (one-eighth of a gallon)
This method makes it easy to calculate the gallon equivalent of any fluid ounce measurement.
How to Convert Gallons to Ounces
To convert gallons to ounces, multiply by 128:
Gallons × 128 = Ounces
For example:
- 2 gallons × 128 = 256 ounces
- 3 gallons × 128 = 384 ounces
- 0.5 gallons × 128 = 64 ounces
This formula helps determine the total fluid ounces in a specific number of gallons.
Comparing the US Gallon and the UK (Imperial) Gallon
