What Is a Quart?

You may see quarts as measurements for milk or ice cream at the grocery store or motor oil at an automotive shop.

A quart is a unit of volume, most commonly used to measure liquid measurements in the U.S. and Great Britain, although a quart can be used for dry measurements in the U.S. We’ll get into that later.

Merriam-Webster defines a quart as “a unit of capacity equal to ¼ gallon or 1/32 bushel.” The abbreviation for quarts is qt. One quart equals 4 cups, 2 pints, or ¼ of a gallon. 

The term quart was used in Middle English and came from the Anglo-French quarte, which came from the Latin quartus meaning “fourth.

Note: U.S. liquid quarts differ from U.S. dry or imperial gallons. We will cover dry and imperial gallons in a section below.

What Is a Gallon?

Milk, water, and gas are commonly sold in gallons. 

A gallon is a unit of volume used to measure large volumes. In comparison, quarts measure smaller volumes.

The term gallon comes from the Middle English galun, galon, galoun, a measurement of liquid, which was borrowed from Anglo-French jalon, galon, galun, derived from Old French jal-, the based of jaloie “container for liquids, bucket.” The Anglo-French galon comes from the base of Medieval Latin galeta meaning “wine vessel, liquid measure.”

Merriam-Webster defines a gallon as “a unit of liquid capacity equal to 231 cubic inches or four quarts.” The abbreviation for gallons is gal. One gallon equals 16 cups, 8 pints, or 4 quarts.

Note: U.S. liquid gallons differ from U.S. dry or imperial gallons. We will cover dry and imperial gallons in a section below.

Dry vs. Liquid Quarts and Gallons

In the U.S., quarts and gallons measure the volume of liquid and dry ingredients. Dry quarts and gallons are used to measure dry volume, while liquid quarts and gallons are used to measure liquid volume. 

In the U.S., a dry quart equals ¼ of a dry gallon or 1.101220942715 liters. A liquid quart equals ¼ of a liquid gallon or 0.946353 liters. A liquid quart is slightly smaller than a dry quart.

For easy reference, here is what a U.S. dry quart is equal to:

  • 1/32 U.S. bushels
  • ⅛ U.S. pecks
  • ¼ U.S. dry gallons
  • 2 U.S. dry pints
  • 67.200625 cubic inches
  • 1.101220942715 liters
  • 38.7572mperial fluid ounces

A dry gallon is also known as a grain or corn gallon. A dry gallon is equal to 4 dry quarts or 4.4 liters. A liquid gallon is 14.1% smaller than a dry gallon. 

Here is a list of dry gallon equivalents:

  • 0.125 U.S. bushels
  • 0.5 U.S. pecks
  • 4 dry quarts
  • 8 dry pints
  • 268.8025 cubic inches
  • 4.4 liters
  • 155.0288 fluid ounces

What Is an Imperial Quart?

An imperial quart, used to measure liquid and dry ingredients, is equal to one-quarter of an imperial gallon. It is a unit of volume in the imperial system.

An imperial quart is equal to:

  • 2 imperial pints
  • 40 imperial fluid ounces
  • 1.1365225 liters
  • 69.355 cubic inches
  • 38.430 U.S. fluid ounces

One U.S. liquid quart equals 0.83267384 imperial quarts. One imperial quart equals 1.20095042 U.S. quarts. To convert U.S. quarts to imperial quarts, multiply the volume by 0.83267384 or divide the volume by 1.20095042.

Use this formula:

Imperial quarts: U.S. quarts x 0.83267384 

Examples:

1 U.S. quart x 0.83267384 = 0.83267384 imperial quarts

5 U.S. quarts x 0.83267384 = 4.1633692 imperial quarts

10 U.S. quarts x 0.83267384 = 8.3267384 imperial quarts

50 U.S. quarts x 0.83267384 = 41.633692 imperial quarts

100 U.S. quarts x 0.83267384 = 83.267384 imperial quarts

You can also use this formula:

Imperial quarts = U.S. quarts ÷ 1.20095042

Examples:

1 U.S. quart ÷ 1.20095042 = 0.83267384 imperial quarts

5 U.S. quarts ÷ 1.20095042 = 4.1633692 imperial quarts

10 U.S. quarts ÷ 1.20095042 = 8.3267384 imperial quarts

50 U.S. quarts ÷ 1.20095042 = 41.633692 imperial quarts

100 U.S. quarts ÷ 1.20095042 = 83.267384 imperial quarts

What Is an Imperial Gallon?

An imperial gallon, used to measure liquid and dry ingredients, equals 4 imperial quarts. It is part of the imperial system of measurements.

An imperial gallon is 1.2009499204287 U.S. gallons. A U.S. gallon is equal to 0.83267384 imperial gallons. An imperial gallon is about 3.2% larger than a dry gallon.

An imperial gallon is equal to:

  • 4 imperial quarts
  • 8 imperial pints
  • 160 imperial fluid ounces
  • 4.54609 liters
  • 277.419 cubic inches
  • 153.72159891488 U.S. fluid ounces

To convert imperial gallons to U.S. gallons, multiply the volume by 1.2009499204287.

U.S. gallons = Imperial gallons x 1.2009499204287

Examples:

1 imperial gallon = 1 x 1.2009499204287 = 1.2009499204287 U.S. gallons

2 imperial gallons = 2 x 1.2009499204287 = 2.40189984086 U.S. gallons

3 imperial gallons = 3 x 1.2009499204287 = 3.60284976129 U.S. gallons

5 imperial gallons = 5 x 1.2009499204287 = 6.00474960214 U.S. gallons

10 imperial gallons = 10 x 1.2009499204287 = 12.0094992043 U.S. gallons

100 imperial gallons = 100 x 1.2009499204287 = 120.094992043 U.S. gallons

You can also use this formula:

U.S. gallons = Imperial gallons ÷ 0.83267384

1 imperial gallon = 1 ÷ 0.83267384 = 1.2009499204287 U.S. gallons

2 imperial gallons = 2 ÷ 0.83267384 = 2.40189984086 U.S. gallons

3 imperial gallons = 3 ÷ 0.83267384 = 3.60284976129 U.S. gallons

5 imperial gallons = 5 ÷ 0.83267384 = 6.00474960214 U.S. gallons

10 imperial gallons = 10 ÷ 0.83267384 = 12.0094992043 U.S. gallons

100 imperial gallons = 100 ÷ 0.83267384 = 120.094992043 U.S. gallons

Common Units for Measuring Capacity

Capacity refers to the amount of a substance a container can hold. For example, juice, oil, or gas containers are objects that show capacity. Volume is the amount of space that a substance or object occupies.

Here are common units used to measure capacity in the U.S. customary measurement system from smallest to largest:

  • Fluid ounces (fl oz): A fluid ounce is a unit equal to ⅛ of a cup. A fluid ounce of water at 62º F weighs about one ounce. 
  • Cups (c): A cup is a unit equal to 8 fluid ounces. A standard measuring cup measures one cup.
  • Pints (pt): Pints are units that equal 2 cups or 16 fluid ounces. Ice cream is commonly measured in pints.
  • Quarts (qt): A unit equal to 4 cups or 32 fluid ounces. Quarts are commonly used to measure volumes of milk.
  • Gallons (gal): A unit that equals 4 quarts or 128 fluid ounces. Gasoline prices are usually listed per gallon.

These measurement units can be used to illustrate the capacity of an object, but there are cases where it makes more sense to use a certain unit.

For example, gallons usually describe high-volume substances such as water in a pool or gas for your car. Fluid ounces are usually reserved for smaller-capacity items such as perfume or beverages.

How Many Quarts Are in a Gallon?

There are 4 quarts in one gallon.

How to Convert Quarts to Gallons

To convert quarts to gallons, divide the volume by 4 or multiply the volume by 0.25.

Gallons = Quarts ÷ 4 or Gallons = Quarts x 0.25

Examples:

1 quart = 1 ÷ 4 = 1 x 0.25 = ¼ gal

2 quarts = 2 ÷ 4 = 2 x 0.25 = ½ gal

3 quarts = 3 ÷ 4 = 3 x 0.25 = ¾ gal

4 quarts = 4 ÷ 4 = 4 x 0.25 = 1 gal

10 quarts = 10 ÷ 4 = 10 x 0.25 = 2 ½ gal

15 quarts = 15 ÷ 4 =  15 x 0.25 = 3 ¾ gal

How to Convert Gallons to Quarts

To convert gallons to quarts, multiply the volume by 4.

Quarts = Gallons x 4

Examples:

1 gallon = 1 x 4 = 4 qt

2 gallons = 2 x 4 = 8 qt

3 gallons = 3 x 4 = 12 qt

5 gallons = 5 x 4 = 20 qt

10 gallons = 10 x 4 = 40 qt

100 gallons = 100 x 4 = 400 qt

How to Measure Quarts and Gallons

If you are cooking or baking, you will need to know the exact measurements to get the recipe just right. Exact measurements are necessary to avoid final products with the wrong texture, consistency, moistness, and form.

If you are measuring liquid ingredients, use measuring cups that have the pour spout design for easy transfer from a cup to a larger container without spilling.

If you are measuring dry ingredients, use measuring cups without the spout. They will have a flat top and smooth brim. This allows you to scrape the excess from the top.
