How Many Fluid Ounces in a Gallon?
The answer to this question “How many fluid ounces in a gallon?” is simple, if you mean:
US System: 1 gallon = 128 fluid ounces
UK System: 1 gallon = 160 fluid ounces
To understand the answer you should know about these terms first.
What is a Gallon?
People need to measure volume when they buy a liquid, such as gasoline. When they fill up their car’s gas tank, they buy a certain number of gallons of gas.
A gallon is a measurement of liquid volume. It comes from an old word “Galleta”, which meant “Bucket”. In olden times, when you bought a gallon of something, you were really buying a bucketful. A gallon is about the same volume as 230 cubic inches. The abbreviation for gallon is “gal”.
What is a Fluid Ounce?
A fluid ounce is a unit of measurement. Fluid Ounces are used to measure liquid capacity. The abbreviation for ounce is “fl. oz”. A fluid ounce is a standard unit of the volume used in the United States & United Kingdom; 1 fluid ounce is the same as 1 fl. oz.
So, it is known as Fluid Ounce which is commonly used to measure the liquid capabilities. There are different other types of the ounces as well as an avoirdupois ounce, troy ounce, tower ounce.

How Many Quarts in a Gallon?
The answer to this question “How many quarts in a gallon?” is simple, if you mean:
1 gallon = 4 quarts
To understand the answer shortly you should know about these terms first.
What is a Quart?
A quart is a unit of liquid measurement. One quart is two pints. Each pint is two cups (0.5 L). That means one quart has four cups.
Another way that we use quarters of something is when we measure milk, water, petrol, or other liquids that pour, like syrup or vinegar or ginger ale.
One quart is really a nickname for one fourth or one quarter of a gallon. Every gallon will fill 4 quart bottles. One half of a quart is what we call a pint. So to measure liquids just remember 2 pints make 1 quart and 4 quarts make 1 gallon.
US and UK Systems of Liquid Measurement
In the first place, the US bushel, gallon, quart, and fluid ounce differ from the corresponding UK units. A British Imperial quart is equal to 1.13 liters (or 40 fluid ounces), whereas a quart in the US Customary System is 0.94 L (or 32 fluid ounces). A gallon in the British Imperial System is equal is 4.54 liters (or 160 fluid ounces) while a US gallon is equal to 3.78 L (or 128 fluid ounces).
The US gallon is divided, into 4 liquid quarts. All the units of capacity mentioned thus far are larger in the UK system than in the US system. But the UK quart is divided into 40 fluid ounces, while the US quart is divided into 32 fluid ounces, and the UK fluid ounce is smaller than the US fluid ounce.
Measurement Conversion Chart
Gallon and quart are common units of liquid measure though they can also be used to measure dry substances. These liquid measurement units are mostly spread in the USA and Australia. Quart and gallon are also the most common measurements for selling different fluids. For example, milk is sold in gallon or quart containers, and petrol is usually dispensed by gallons. Smaller liquid measures are not often used though one can buy a pint of juice in any grocery store.
These units can also be used in cooking and baking, but as a rule, it is more convenient to measure liquids in pints, cups, tablespoons, fluid ounces, and teaspoons. The following table will help you to convert units.
One Gallon | One Quart | |
Quarts | 4 | 1 |
Pints | 8 | 2 |
Cups | 16 | 4 |
Fluid Ounces | 128 | 32 |
Table-spoons | 256 | 64 |
Tea-spoons | 768 | 192 |

Converting Between Quarts, Gallons, and Milliliters
The process of converting between quarts and milliliters is quite a bit trickier than converting between quarts and gallons since 1 quart is equal to approximately 946.353 milliliters for a US quart. If you are using the imperial quart it is equivalent to 1136.52 milliliters instead. Just multiply the number of quarts by either 946.353 or 1136.52 depending on which quart you are using. The values are different for the two different quarts, so be sure you use the same value consistently and don’t accidentally start using the wrong quart when doing calculations.
1 US quart = 946.353 milliliters
1 imperial quart = 1136.52 milliliters
1 US gallon = 3785.41 milliliters
1 imperial gallon = 4546.09 milliliters
What about converting between the gallon and milliliters? This is essentially the same as converting between quarts and milliliters, except you multiply the number of gallons by 3785.41 for the US gallon and by 4546.09 for the Imperial gallon. Finally, since there are 1000 millimeters in a liter, you can divide these numbers by 1000 to ascertain how many liters you have.

US System: 1 pint = 16 ounces
UK System: 1 pint = 20 ounces
To understand the answer you should know about these terms first.
What is a pint?
A pint is a unit for measuring volume or capacity. It is used for both liquid and dry capacity measurements and it is equivalent to one-eighth of a gallon in both United States and imperial measurement systems although there is slight variation in the true definition of the pint in both systems especially as regards what is a pint in liters. While the British system defines the pint (1/8 of a gallon) as 0.568 liters, the United States Standards puts it at 0.473 liters in case of liquid measurement and 0.551 liters for dry volume. The abbreviation for pint is “p”.
How to Convert Pints to Ounces?

256 oz ——————–> 12.8 p
How to Convert Pints to Milliliters?
Since the standard international unit for measurement for volume is the milliliter (ml), it is important that you are able to compare other units like the pint to this standard. One milliliter is equivalent to one cubic centimeter (cm3) or 1/1000 liters.
US System: 1 pint = 473 ml
UK System: 1 pint = 568ml
Since a pint is equal to 0.568 liters or 0.473 liters for imperial and US standards respectively, we can compare both units by a simple calculation. Based on this calculation, 1 pint is equal to 473 ml based on United States standards or 568ml according to the British imperial system of measurement.
How to Convert Gallons, Quarts, Pints, and Cups?
In contrast to most of the world, which relies on the metric system, the United States uses a non-uniform system for measuring and dispensing most liquids. A holdover from the system of imperial units, the “US customary system” measures liquid from gasoline to groceries based on the number of fluid ounces. To efficiently manage recipes, formulas and calculate the cost, it is necessary to understand the system for converting pints, quarts, gallons, and cups.
1 pint = 16 ounces
1 pint = 2 cups
Convert cups to pints. Multiply the number of ounces in a cup, which means 8 ounces, by 2. With 1 pint identical to 16 ounces, so 1 pint is equal to 2 cups (2 x 8 = 16).
1 quart = 2 pints
Convert cups or pints to quarts. As there are 32 ounces in a quart, a quart is equal to 4 cups (4 x 8 = 32) or 2 pints (2 x 16 = 32).
1 gallon = 8 pints
Convert the number of cup, pints or quarts to gallons. With a gallon similar to 128 ounces, a gallon is equal to 16 cups (16 x 8 = 128), 8 pints (8 x 16 = 128) or 4 quarts (4 x 32 = 128).

How Many Ounces in a Gallon?
The answer to this question “How many ounces in a gallon?” is simple, if you mean:
US System: 1 gallon = 128 ounces
UK System: 1 gallon = 160 ounces
To understand the answer you should know about these terms first.
What is an Ounce?
The ounce is the smallest measurement of weight. On packages, it is commonly referred to by the abbreviation “oz”‘ which comes from the Spanish and Italian word “Onza”. A slice of bread weighs about 1 ounce.
Ounce originated from Britain in a term to measure portions of food, areal density, paper, postal items, fabric, gloves, and more items. It is known to measure the weight of an item. An ounce is mostly known as a “small part” of an item regarding maths where one ounce is equal to 28.3495 grams.
Difference Between Ounces and Fluid Ounces
There is a lot of ongoing confusion between the terms “ounces” and “fluid ounces”. This is because there are a variety of system measurements used across the world like the Metric System, US Customary, Imperial, English, Natural Units, and Non-Standard Units. Moreover, one has to discern if the item being measured is in dry form or in liquid form because the measurement of weight and volume are two different things.
The ounce and the fluid ounce measurements are often misused by many. In its simplest possible explanation, an ounce is used for dry measurements and the abbreviation for ounce is “oz” while fluid ounce is used to measure fluids and abbreviated as “fl. oz”. This gives us the idea that an ounce is a measurement of weight while the fluid ounce is a measurement of volume.
Ounce to Grams and Fluid Ounce to Milliliters
The term “ounce” means “the twelfth part.” It can also be used in several different systems of measurements, but the most widely used systems for “ounce” is the international avoirdupois ounce and the international troy ounce. This suggests that one ounce is approximately 28.3495 grams. In the same way, we use two systems in measuring fluid ounces. For example, one unit of a fluid ounce is approximately 29.5735 ml using the US Customary system while it is just approximately 28 ml using the Imperial system. This makes one beg for the use of one unified, standard system of measurement which is not entirely applicable today.
Dry oz:
1 oz = lb
1 oz = g
Fluid oz:
1 fl. oz = pint
1 fl. oz = ml
Are Fluid Ounces and Ounces Interchangeable?
Any ambiguity surrounding fluid ounce and ounce units of measurement is understandable since they share the same name, and recipes sometimes are not clear about which type they mean.
Also, a cup of water happens to equal both 8 ounces (in weight) and 8 fluid ounces (in volume), thus you might naturally assume that 1 cup equals 8 ounces of weight universally in recipes.
But no, water is only the exception rather than the rule. Since ounces and fluid ounces are measuring such very different things, they are not often the same for most ingredients. Think of one cup of tomato sauce and one cup of flour; they both occupy the same volume of space (8 fluid ounces), but they have different weights (about 7.9 ounces for the tomato sauce, and about 4 ounces for the flour).
So no, ounces and fluid ounces should not be used interchangeably. Pay close attention when reading your recipe to make sure you’re measuring right!
