How Many Quarts in a Gallon

This might not be so important in the grand scheme of things, but if you have to need to know how many quarts in a gallon, then I am here for you.

I am hoping you would have become that baker or chef or whatever profession it is that will make you seek these sorts of answers. Then voilà! I provide it. That was on a lighter note though but getting on now, let’s get to learn how many quarts in a gallon. Read on and be blessed.

If you’ve been following us long enough now, you know we are big on perspective here. Because we endure you very well understand relevant terms first before we delve into the actual discussion so here we go.

What are Quarts

Wikipedia says that the quart  with the symbol (qt) is an English unit of volume equal to a quarter gallon and that three kinds of quarts are currently used: the liquid quart and dry quart of the US customary system and the imperial quart of the British imperial system

All are roughly equal to one liter. It is divided into two pints or (in the US) four cups. However, the exact size of the quart has varied with the different values of gallons over time and about different commodities.

Because a quart is two pints, in every quart, there  be four cups. Now quart is a pretty good size. If you buy a water bottle, one of those reusable water bottles, that’s usually a quart. A quart is 32 fluid ounces.

Simply put, a quart is a way to measure volume or how much liquid a container can hold.

Don’t miss:

History of Quart

 The quart is based on the gallon, the definition of which has changed throughout history based on the commodity being referenced. The current definition of the US quart is based on the English wine gallon. This same definition was used for the imperial quart up until 1824 when the UK re-defined the imperial gallon.

Current use: The respective versions of the quart are used mainly in the United States and the United Kingdom, though in the UK, the use of the liter is now mandated as a result of metrication.

How Many Quarts in a Gallon

The US Liquid Quarts

The U.S. liquid quart is equal to two liquid pints, or one-fourth U.S. gallon (57.75 cubic inches, or 946.35 cubic cm or liters)

In terms of its closest metric equivalent the liter, a liquid quart is slightly less than a liter (in fact it’s about 0.95 liters).

So, it is safe to say that

1 US liquid quart = 1⁄4 US liquid gallons

                                = 2 US liquid pints
= 4 US liquid cups
= 8 US liquid gills
= 32 US fluid ounces
= 57.75 cubic inches
≡ 0.946352946 liters
≈ 33.307 imperial fluid ounces

The US Dry Quarts

Remember in our definition, we mentioned that they are three kinds of quarts. So here, we will do well to explain what the three of them are.
A dry quarts is a United States dry unit equal to 2 pints or 67.2 cubic inches. quart.

In the United States, the dry quart is equal to one quarter of a US dry gallon, or exactly 1.101220942715 liters.

A dry quart, on the other hand, is actually slightly larger than a liter: it’s about 1.10 liters. Dry quarts are actually used to measure bushels of dry stuff, for example wheat.

Breaking it down some more,

1 US dry quart = 1⁄32 US bushels

= 1⁄8 US pecks
= 1⁄4 US dry gallons
= 2 US dry pints
= 67.200625 cubic inches
≡ 1.101220942715 liters
≈ 38.758 imperial fluid ounces.

The Imperial Quart

The imperial quart, which is used for both liquid and dry capacity, is equal to one quarter of an imperial gallon, or exactly 1.1365225 liters. In the United Kingdom goods may be sold by the quart if the equivalent metric measure is also given. 1 imperial quart. = 1⁄4

The UK’s imperial quart is the biggest of the three, as  it is equal to about 1.14 liters.

1 imperial quart = 1⁄4 imperial gallons

                               = 2 imperial pints
= 40 imperial fluid ounces
≡ 1.1365225 liters
≈ 69.355 cubic inches
≈ 38.430 US fluid ounces

What is a Gallon?

A gallon is a unit of measurement used for liquids such as gasoline, water, and milk in the United States.

It is a volume unit in Imperial and United States Customary systems. The symbol is “gal”.

A gallon is equivalent to 4 quarts of liquid or 3.785 liters and the United States is one of the last countries to use this term.

Though the gallon has roots in the British Imperial Units measurement system, the United Kingdom and most countries around the world have switched to the newer International System of Units.

The gallon can also be defined as a unit of volume in imperial units and the United States customary units. Three different versions are in current use:

  • the imperial gallon (imp gal), defined as 4.54609 liters, which is or was used in the United Kingdom, Ireland, Canada, Australia, and some Caribbean countries;
  • the US gallon (US gal) is defined as 231 cubic inches (exactly 3.785411784 L), which is used in the US and some Latin American and Caribbean countries; and
  • the US dry gallon (“usdrygal”), defined as 18 US bushel (exactly 4.40488377086 L).
  • 1 gal = 4 quart = 8 pints = 16 cups = 128 ounces = 256 TBs

So consequently,  the same pattern in quarts, applies to gallons as a liquid gallon is smaller than a dry gallon, which is smaller than a UK “imperial gallon.”

A US (liquid) gallon is about 3.79 liters, a US dry gallon is 4.4 liters, and an imperial gallon is 4.55 liters.

Origin of Gallon

The term gallon most closely originates from “galon” in Old Northern French and developed as a system for measuring wine and beer in England, resulting in measures such as the wine gallon, ale gallon, and imperial gallon.

The sizes of gallons used in these two systems were different from each other: the first was based on the wine gallon (equal in size to the US gallon), and the second one was either the ale gallon or the larger imperial gallon.

Current use: In the United States (US), gallons are often used for larger containers, such as half gallon tubs of ice cream or one-gallon cartons of milk. Gallons are also widely used in fuel economy expression in the US, as well as some of its territories. The imperial gallon is used even more sparingly than the US gallon, with most countries around the world using liters when referencing fuel.

The US and UK Gallon

Here, we will better explain the differences between the US and the UK gallons, as that is a vital consideration when discussing how many quarts in a gallon.

In 1824, the British adapted the Imperial measure in which the gallon is based on 10 pounds or 277.42 cubic inches of water. As a result, the U.S. gallon is 83.3 percent of the Imperial gallon or better put, the Imperial gallon is about one-fifth of 20 percent greater in volume than the American gallon.

Differences Between US and UK Gallon

Like earlier mentioned, a US gallon is made up of 7.58 bottles of water while a UK gallon is made up of 9.10 bottles of water. That clearly shows the UK gallon is bigger than that of the US.

In the Americas, a gallon is equivalent to 128 fluid ounces or 3.785 liters (American spelling). But in the UK, it’s 160 fluid ounces or 4.546 litres (British spelling).

How many Quarts in a Gallon

A quart contains 4 cups or 2 pints while a gallon contains 16 cups or 8 pints. Thus, there are 4 quarts (qt) in 1 gallon (gal).

Both quarts and gallons are part of the US customary and imperial systems of measurement. The unit quart gets its name from the Latin quartus, meaning “one-quarter,” so the unit is based on being one-quarter of a gallon.

How To Convert From Quarts to Gallons

In converting between quarts and gallons, one needs to remember the relationship between a quart and a gallon.  So, just remember that a quart is a quarter of a gallon, An illustration is given below;

1 quart =  gallon

1 gallon = 4 quarts

To convert a quart measurement to a gallon measurement, divide the volume by the conversion ratio.

Since one gallon is equal to 4 quarts, you can use this simple formula to convert.

gallons = quarts ÷ 4

The volume in gallons is equal to the quarts divided by 4.

For example, here’s how to convert 5 quarts to gallons using the formula above.
5 qt = (5 ÷ 4) = 1.25 gal

 Meanwhile, converting from gallons to quarts, requires you to multiply by 4.

The formula is;

Quarts = Gallons x 4
I.e the volume in quarts is equal to the gallons value multiplied by 4.

For example, here’s how to convert 12 gallons to quarts, using the formula above.

12 gal × 4 = 48 qt

One thing worthy of note is they are various definitions of a gallon, but in all these definitions, the relationship between a quart and a gallon (4 quarts: 1 gallon) remains the same.

You just have to ensure that you are converting between quarts and gallons in the same system of measurement, because if you are converting between US quarts and imperial gallons, then the relationship is not the same because of  the units to millilters (mL)

  • 1 US gallon = 3785.411784 mL
  • 1 US quart = 946.352948 mL
  • 1 imperial gallon = 4546.09 mL
  • 1 imperial quart = 1136.5225 mL

So, if you are converting from quarts to gallons in different systems, you would need to take the above relationships into consideration.

Volume Measurements in the US Customary System

Volume is the quantity of three-dimensional space occupied by a liquid, solid, or gas. Common units used to express volume include liters, cubic meters, gallons, milliliters, quarts, teaspoons, and ounces, though many other units exist.

The International System of Units (SI) standard unit of volume is the cubic meter (m3) and the metric system uses the liter (L) as a volume unit. One liter is the same volume as a 10-centimeter cube.

The most significant units of volume in the US Customary System of Measurements are,

  1. cups
  2. pints
  3. quarts
  4. gallon

Truth is, we use these measurement parameter for liquid measurements every single day. Whether we’re cooking, gardening, or filling a pool, we just have to know the right unit to use.

In trying to fill a swimming pool,  a gallon will suffice  more  than a cup would. Considering, that a cup is a small amount, and a gallon is quite large.

When cooking, chances are you’re probably going to use more cups and pints than you are going to use a gallon unless you’re making a large amount of something. Therefore, if you measure the water in the aquarium, you measure it with a gallon. If you’re measuring the amount of soup that you’re making,  then it is probably a cup.

Knowing the right unit of volume to use, is just key as you can end up adding an excess measure of liquid into recipe or anything else for that matter, if you are not careful.

Things Commonly Measured in Quarts

1. Drinks measurement in Quart

Many beverages sold in larger containers are often measured in liters. A liter is just over 1/4 of a gallon, so many drinks, such as water, juice, or milk, are often measured and sold in cartons or bottles of several liters and a litre approximately equals a quarts.

2.Paint measurement in Quart

In the United States, most paint is sold in quart, gallon, or 5-gallon sizes, but because it’s sold in larger quantities, paint can also be sold in liter increments.

 3. Ziplock Bags measurement in QuartHow much a plastic zip bag, freezer bag, or reusable snack bag can hold is often marked in liters.

This is because the liter is an intermediate size, falling between a gallon, which is larger, and ounces, which are a bit smaller.

4.Shampoo Bottles measurement in Quart

Shampoo bottles come in all shapes and sizes, which means they can hold various amounts of liquid. However, many shampoo bottles are designed to hold about one liter of liquid soap.

You can tell exactly how much the bottle holds by checking the label. If it’s close to 32 ounces, the bottle holds about one liter, and that is a quarts.

The long and short of it all is that four quarts  equals a gallon. So if you ever wondered how many quarts equals a gallon?we hope we have answered you satisfiably.
