Understanding the conversion between ounces and gallons is essential, especially for cooking, measuring liquids, or converting quantities in recipes. This article provides complete, to-the-point information on how many ounces are in a gallon, along with a conversion table and clear definitions for better understanding.
Definition of Gallon and Ounce
What is a Gallon?
A gallon is a unit of liquid measurement used primarily in the United States and a few other countries. It is part of the US customary system of measurement. In the US, one gallon equals 128 fluid ounces. There are two types of gallons:
- US Liquid Gallon: Equal to 128 fluid ounces.
- Imperial Gallon (used in the UK and other countries): Equal to 160 fluid ounces.
What is an Ounce?
An ounce (oz) is a unit of weight and volume. When measuring liquids, we refer to fluid ounces. A fluid ounce measures the volume of a liquid, and it is different from an ounce that measures weight. In this context, we’ll focus on fluid ounces for liquid measurements.
How Many Ounces in a Gallon?
- In the US: 1 US gallon = 128 US fluid ounces.
- In the UK (Imperial System): 1 Imperial gallon = 160 Imperial fluid ounces.
This difference occurs because the US gallon is smaller than the Imperial gallon, which is still used in countries like the UK and Canada.
Conversion Table: Ounces to Gallons
The table below shows how many ounces convert to fractions of gallons in both the US and Imperial systems:
| Ounces (oz) | US Gallons | Imperial Gallons |
|---|---|---|
| 1 oz | 0.0078 gal | 0.00625 gal |
| 8 oz (1 cup) | 0.0625 gal | 0.05 gal |
| 16 oz (1 pint) | 0.125 gal | 0.1 gal |
| 32 oz (1 quart) | 0.25 gal | 0.2 gal |
| 64 oz | 0.5 gal | 0.4 gal |
| 128 oz | 1 gallon | 0.8 gal |
| 160 oz | 1.25 gal | 1 gallon |
How to Convert Ounces to Gallons
To convert fluid ounces to gallons, use the following formulas:
For US Gallons:
Gallons = Ounces/128
Example: If you have 64 ounces of water, you can convert it to gallons by dividing 64 by 128.
64÷128=0.5 gallons
For Imperial Gallons:
Gallons =
Example: If you have 80 ounces, the conversion would be:
80÷160=0.5 gallons (Imperial)
Quick Conversions
- 1 US gallon = 128 US fluid ounces.
- Half gallon (US) = 64 fluid ounces.
- 1 Imperial gallon = 160 Imperial fluid ounces.
- Half gallon (Imperial) = 80 Imperial fluid ounces.

Common Uses of Gallons and Ounces
- In Cooking: Recipes often call for gallons or ounces to measure liquids such as water, milk, or oil. Accurate measurements ensure the right consistency and flavor.
- Fuel Measurement: Gallons are also used to measure fuel, such as gasoline. Gas stations in nations that use the Imperial system will show the price per Imperial gallon.
- Hydration Tracking: Many people track their daily water intake in ounces. Understanding how many ounces are in a gallon helps people aim for the recommended daily water intake (approximately half a gallon or 64 ounces).
How Many Fluid Ounces in a Gallon?
To determine how many fluid ounces of water bottles there are in a gallon, you first need to know the size of the water bottle in fluid ounces. The most common water bottle sizes are 16.9 fluid ounces (500 ml), 12 fluid ounces, and 8 fluid ounces.
1 US gallon = 128 fluid ounces.
Now, we’ll break it down by the different bottle sizes to determine how many bottles make up a gallon.
For 16.9 oz (500 ml) water bottles:
To find how many 16.9-ounce bottles make a gallon:
128 oz / 16.9oz
So, there are about 7.57 bottles of 16.9 oz of water in a gallon.
For 12 oz. water bottles:
For 12-ounce bottles:
128oz / 12oz = 10.67bottles
There are about 10.67 bottles of 12 oz of water in a gallon.
For 8 oz. Water Bottles:
For 8-ounce bottles:
128 oz / 8 oz =16bottles
There are exactly 16 bottles of 8 oz of water in a gallon.
Summary:
- 16.9 oz bottles: ~7.57 bottles per gallon.
- 12 oz bottles: ~10.67 bottles per gallon.
- 8 oz bottles: 16 bottles per gallon.
How Much Water Should I Drink a Day?
