How many gallons Makes 4 quarts?

To answer the question “How many gallons makes 4 quarts?”, we first need to understand the relationship between gallons and quarts as units of liquid measurement.

Key Takeaways

  • 1 gallon is equal to 4 quarts.
  • Therefore, 4 quarts is equivalent to 1 gallon.
  • Quarts and gallons are standard units of liquid measurement in the US customary system.
  • 1 gallon contains 4 quarts, 8 pints, or 128 fluid ounces.
  • Understanding liquid conversions between gallons, quarts, pints, cups and ounces is useful for cooking, mixing drinks, and other everyday applications.

The Gallon Unit of Measurement

A gallon is a standard unit of liquid measurement in both the US customary system and the imperial system. In the US customary system, 1 gallon is equal to 231 cubic inches, or exactly 128 fluid ounces. The US gallon is commonly used in the United States and is about 20% smaller than the imperial gallon used in the United Kingdom and many other countries. The imperial gallon is equal to about 1.2 US gallons.

The US gallon is divided into 4 quarts, 8 pints, or 128 fluid ounces. This makes it easy to convert between gallons and smaller units of fluid measurement.

Key Gallon Conversions

  • 1 gallon = 4 quarts
  • 1 gallon = 8 pints
  • 1 gallon = 16 cups
  • 1 gallon = 128 fluid ounces
  • 1 gallon = 3.79 liters

Knowing these key gallon conversions allows you to translate between gallons and other units both larger (like liters) and smaller (like cups and ounces). Gallons are commonly used to measure volumes of liquid from gallons of milk at the grocery store to gallons of gasoline at the pump.

The Quart Unit of Liquid Measurement

A quart is an imperial unit of volume equal to one quarter of a gallon. It is divided into two pints or four cups. Since the US gallon contains 128 fluid ounces, one quart in the US customary system is equal to 32 fluid ounces. An easy way to remember the size of a quart is that it is almost equal to one liter (with 1 liter measuring 33.81 ounces).

Key Quart Conversions

  • 1 quart = 2 pints
  • 1 quart = 4 cups
  • 1 quart = 32 fluid ounces
  • 1 quart = 0.946 liters

Quarts are a common unit for measuring volumes of liquids from quarts of milk or juice to quarts of oil for a car. Quart-sized containers are popular for products like yogurt, ice cream and bottled juices and teas.

The Relationship Between Gallons and Quarts

Now that we understand the definitions of gallons and quarts, we can examine the relationship between these two units of liquid measurement:

  • 1 gallon is equal to 4 quarts
  • 1 quart is equal to 1/4 gallon

This conversion is easy to remember if you think of a gallon as divided into four equal parts, each part being a quart. Each time you go up by a quart, you add one fourth of a gallon. So 2 quarts equals half a gallon, 3 quarts is 3/4 of a gallon, and 4 quarts makes 1 full gallon.

Gallons to Quarts Conversion Table

Gallons Quarts
1 gallon 4 quarts
2 gallons 8 quarts
3 gallons 12 quarts
4 gallons 16 quarts
5 gallons 20 quarts

This table illustrates how many quarts are present when you count gallons. For example, 2 gallons contains 8 quarts, 3 gallons contains 12 quarts, and so on.

Quarts to Gallons Conversion Table

Quarts Gallons
1 quart 0.25 gallons
2 quarts 0.5 gallons
3 quarts 0.75 gallons
4 quarts 1 gallon
8 quarts 2 gallons
12 quarts 3 gallons
16 quarts 4 gallons

This table shows the number of gallons for a given number of quarts. For instance, 2 quarts equals 0.5 gallons, 4 quarts is 1 gallon, 8 quarts is 2 gallons, and so on.

Practical Examples

Understanding the relationship between quarts and gallons is useful any time you need to convert between these units in real-life situations:


  • Many recipes call for ingredient amounts in cups, quarts or gallons. Knowing how these convert allows you to measure the correct quantities.
  • If a recipe needs 2 gallons of water, you would measure out 8 quarts of water.
  • If you only have a 2-quart container and need 1 gallon of milk for a recipe, you would fill the container twice.

Mixing Drinks

  • Cocktail recipes may list ingredient amounts in ounces, cups, pints or quarts. Converting between these is needed to measure the proper proportions.
  • If a punch recipe calls for 1 gallon of fruit juice, you could measure out 4 quarts of juice.
  • If you only have a quart-sized container, you could make a single serving by dividing all the recipe amounts by 4.

Everyday Tasks

  • Understanding gallon and quart equivalents makes it easy to convert container sizes while shopping.
  • If you have a quart of milk left and a recipe calls for half a gallon, you know you only have half the required amount.
  • When buying paint for a room, you can use the quart-to-gallon conversion to make sure you purchase enough.

Quick Quarts to Gallons Conversions

For quick reference, here are some of the most common quarts to gallons conversions:

  • 2 quarts = 0.5 gallons
  • 4 quarts = 1 gallon
  • 8 quarts = 2 gallons
  • 16 quarts = 4 gallons
  • 24 quarts = 6 gallons
  • 32 quarts = 8 gallons

Knowing these handy conversions allows you to quickly translate between quarts and gallons for common amounts you may need to measure or calculate.

Converting Gallons and Quarts in Recipes and Projects

Being able to convert between gallons and quarts is extremely helpful when following recipes, doing arts and crafts projects, mixing paint, and any other tasks that involve precise liquid measurement.

Recipe Example

A bread recipe calls for 2 quarts of water. You only have gallon jugs – how much should you measure?

  • 2 quarts = 0.5 gallons
  • So you would measure out half a gallon, which is 2 quarts.

Craft Project Example

You need 5 quarts of Mod Podge glue for a decoupage project. At the store Mod Podge is sold in gallons. How many gallons should you buy?

  • 5 quarts = 1.25 gallons
  • So you need slightly more than 1 gallon – buy 2 gallons to have more than enough.

Converting Metric Amounts

The conversions discussed so far apply to US customary units. For scientific, medical, and international applications, metric units like liters and milliliters are more common.

Here are some key conversions between metric and US customary units:

  • 1 gallon = 3.79 liters
  • 1 liter = 1.057 quarts
  • 1 milliliter = 0.034 fluid ounces

So if a medical dosage is 0.5 liters, that equals roughly 2 cups or 1 pint. Or if you need 250 mL of chemicals for a science experiment, that is close to 1 cup.

Converting Between Larger and Smaller Units

We’ve focused mainly on converting between gallons and quarts, but similar relationships apply when converting between other unit sizes:

  • Gallons to pints – multiply gallons by 8 to get pints
  • Quarts to cups – multiply quarts by 4 to get cups
  • Cups to ounces – multiply cups by 8 to get fluid ounces

Knowing the conversions above helps you translate any liquid quantity between larger and smaller units of measure.


In summary, the answer to “How many gallons makes 4 quarts?” is:

  • 1 gallon is equal to 4 quarts
  • So 4 quarts contains 1 gallon of liquid volume

Understanding liquid conversions between gallons, quarts, pints, cups and ounces is extremely useful any time you need to measure volumes for cooking, mixing drinks, DIY projects, and many other applications. With practice, translating between different units of liquid measurement becomes quick and easy.
