What is a Quart?

A quart is an imperial and United States customary unit of volume. It is equal to 2 pints, 4 cups, or 32 fluid ounces. A quart is precisely equal to 0.946352946 liters. It is exactly 1⁄4 of a gallon.

The quart was originally defined as a quarter of a gallon for both liquid and dry measure. Today, it is primarily used as a unit of liquid volume in the US and is mainly used for cooking measurements. Many American recipes call for ingredients like milk, broth, oil, and water in quarts and cups.

Quart Equivalents

Here are some key equivalents for the quart:

  • 1 quart = 2 pints = 4 cups
  • 1 quart = 32 fluid ounces
  • 1 quart = 0.946352946 liters
  • 1 quart = 1⁄4 gallon

So a quart is simply defined as being equal to 32 fluid ounces. No matter what substance you are measuring – water, oil, milk, etc. – 32 oz will always amount to 1 quart exactly.

Understanding Fluid Ounces

The fluid ounce is a unit of volume typically used for measuring liquids. One fluid ounce is equal to exactly 28.413 ml or 1.804688 cubic inches. The US customary fluid ounce is derived from the volume of 1 ounce of water at room temperature.

Fluid ounces are commonly used alongside quarts, cups, pints, and gallons for volume measurements in cooking and recipes in the US. Many liquids like cream, soda, beer, and more are sold in fluid ounce sizes.

There are some key facts to know about US fluid ounces:

  • 1 US fluid ounce = 1.804688 cubic inches
  • 1 US fluid ounce = 28.413 ml
  • 1 pint = 16 fluid ounces
  • 1 quart = 32 fluid ounces
  • 1 gallon = 128 fluid ounces

So a quart contains 32 of these fluid ounce measurements. You can equate any volume in fluid ounces to quarts by dividing by 32.

Comparing Quarts and Liters

While quarts are commonly used as liquid measurements in the US, the rest of the world primarily uses the metric system. So liters are more commonly used outside America.

Here’s how quarts and liters compare:

  • 1 quart = 0.946352946 liters
  • 1 liter = 1.05669 quarts

So while they are close approximations, quarts and liters do not exactly convert. This table compares some other key quart and liter conversions:

Quarts Liters
1 quart 0.946352946 liters
2 quarts 1.892705 liters
4 quarts 3.78541 liters
8 quarts 7.57082 liters

Quarts in Cooking

Quarts are commonly used in cooking recipes and food preparation in the United States. Some examples include:

  • Quarts of milk or buttermilk
  • Quarts of water
  • Quarts of broth or stock
  • Quarts of ice cream
  • Quarts of berries or other fresh produce
  • Quarts of juice like orange juice
  • Quarts of oil for frying
  • Quarts of honey, maple syrup, or other liquids

Many recipes will list ingredients like milk, water, stock, juice, and oil in quarts and cups. So it’s helpful for home cooks to understand that 32 fluid ounces equals 1 quart.

Quart Containers

There are many food containers and instruments that use quarts:

  • Quart sized jars or containers for canning
  • Quart sized freezer bags
  • Quart sized pitchers or mixing bowls
  • Quart sized mason jars or other glass jars

These quart sized containers hold 32 fluid ounces exactly. Canning jars, freezer bags, and mason jars labelled as “quart” size will hold 1 quart volume of fruits, vegetables, liquids, or other foods.

Metric Conversions

For those using the metric system, here are some key quart to milliliter and liter conversions:

  • 1 quart = 946.353 ml
  • 32 fluid ounces = 946.353 ml
  • 1 liter = 1050 ml
  • 1 quart = 0.946353 liters

So while a quart isn’t an even 1000 ml like a liter, it’s just under at about 950 ml. The exact conversion is:

  • 1 quart = 946.352946 ml

This table shows some quart to milliliter conversions:

Quarts Milliliters
1 quart 946.352946 ml
2 quarts 1892.705 ml
3 quarts 2839.058 ml
4 quarts 3785.411 ml

Quarts to Cups

Another common quart conversion is to cups. Since cups are a convenient cooking unit, knowing how many cups are in a quart is handy. The conversion is:

  • 1 quart = 4 cups

This makes sense since a quart is equal to 32 ounces. And 1 cup equals 8 fluid ounces. So with 4 cups in a quart, each containing 8 ounces, you get the 32 ounces total that make up a quart.

Here is a cups to quarts conversion chart:

Cups Quarts
4 cups 1 quart
8 cups 2 quarts
12 cups 3 quarts
16 cups 4 quarts

Pint to Quart Conversions

Another handy conversion to know is pints to quarts. Here is how pints and quarts compare:

  • 1 quart = 2 pints
  • 1 pint = 16 fluid ounces
  • 1 quart = 32 fluid ounces

So since there are 16 ounces in 1 pint, and 32 ounces in 1 quart, you need 2 pints to equal 1 quart. Some other useful pint-quart conversions include:

Pints Quarts
2 pints 1 quart
4 pints 2 quarts
8 pints 4 quarts
16 pints 8 quarts

Quarts in a Gallon

Since a gallon contains 128 fluid ounces, and a quart contains 32 fluid ounces, a gallon equals 4 quarts. The conversions are:

  • 1 gallon = 4 quarts
  • 1 quart = 1/4 gallon

The number of quarts in a gallon can be useful when converting between gallon and quart cooking measurements. For example:

  • 1 gallon milk = 4 quarts milk
  • 2 gallons broth = 8 quarts broth
  • 4 quarts ice cream = 1 gallon ice cream

Quarts to Weight Conversion

In some recipes or food processing applications, you may need to convert between quarts and pounds. Here are some common liquid quart to pound conversions:

Liquid Quarts Pounds
Water 1 quart 2 pounds
Milk 1 quart 2.15 pounds
Honey 1 quart 3.55 pounds
Oil 1 quart 1.92 pounds

So for water, 1 quart = 2 pounds exactly. For milk, 1 quart is about 2.15 pounds and honey 1 quart = about 3.55 pounds. Converting quarts to pounds or other mass units can be useful for shipping, carrying, or calculating nutrition info.

Quart Sizes of Common Items

Here are some examples of everyday objects that are commonly sold in quart sizes:

  • Quart of milk
  • Quart of orange juice or other juices
  • Quart of ice cream
  • Quart of yogurt
  • Quart sized bottled waters
  • Quart sized bags of dog food
  • Quart sized containers of motor oil
  • Quart sized paint cans
  • Quart sized cartons of soup or broth
  • Quart sized plastic food containers

So when you see an item labeled as “quart size”, you know that means it contains 32 fluid ounces.


What is the difference between a quart and a liter?

A key difference between quarts and liters is that quarts are a US customary unit while liters are a metric unit. A quart equals 32 fluid ounces while a liter equals 1000 milliliters. They are close approximations but not equal. 1 liter = 1.05669 liquid quarts.

How many cups are in 1 quart?

There are 4 cups in 1 quart. Since 1 cup = 8 fluid ounces and 1 quart = 32 fluid ounces, dividing 32oz by 8oz per cup gives you 4 cups.

How many pints are in a quart?

There are 2 pints in 1 quart. Since 1 pint = 16 oz and 1 quart = 32 oz, dividing 32oz by 16oz per pint equals 2 pints per quart.

How do you convert quarts to gallons?

To convert quarts to gallons, divide the number of quarts by 4, since there are 4 quarts in 1 gallon. For example, 8 quarts divided by 4 equals 2 gallons.

How do you convert quart to pounds?

To convert quarts to pounds, multiply the number of quarts by the appropriate conversion factor for the liquid. For water, multiply quarts by 2 to get pounds. For milk, multiply quarts by 2.15. For oil, multiply quarts by 1.92 to convert to pounds.


In summary, a quart is defined as equal to 32 fluid ounces. No matter what liquid you are measuring, 32 ounces will give you exactly 1 quart volume. Quarts can be converted to related cooking units like cups and pints, or to metric units like milliliters and liters. A key quart fact to remember is that 32 ounces equals 1 quart.
