While getting your measurements correct might seem easy at surface level, the case is not usually the same when you have a different measuring tool that’s different from what a particular recipe or cookbook instructs, probably due to geographic location or country measurement system. In such scenario, how do you get the right measurement for your unique recipe?

A great solution to such conflicting measurement problem as related to Quarts and Fluid Ounces is to either use a Quarts to Fluid Ounces converter or do the math yourself. To be able to calculate or convert Fluid ounces Quarts or Quarts to Fluid Ounces, you first need to know how many Oz is in a Quart or interchangeably, how many fluid ounces in a quart.

How Many Ounces in a Quart?

There are 32 ounces in 1 quart, using the US standard system of measurement and 40 ounces in a quart using the Imperial system of measurement. 1 US liquid quart is equal to 32 US fluid ounces. 1 US dry quart weighs about 37.23 oz. This is also equivalent to 1/4th of a gallon, or 2 pints. Formula: multiply the volume value by 32.

Let’s break that down:

  • There are 32 ounces in one quart, using the US standard system of measurement.
  • 1 quart is the same as 32 fluid ounces of liquid.
  • A quart of liquids weighs 32 ounces (U.S. system).
  • To convert from ounces (oz) to quarts (qt), multiply the volume value by 32.

Generally, 1 Ounce = 0.03125 Quarts. 1 U.S. fluid ounce is 1/128th of a U.S. gallon. It is not the same as an ounce of weight or an Imperial fluid ounce. This should not be confused with the Imperial quart, which is about 20% larger.

If you are converting from a US liquid quart to US fluid ounce, then there are 32 fluid ounces in a quart. But if the conversion is between Imperial quarts and Imperial fluid ounces, then there are 40 Imperial fluid ounces in an Imperial quart.

  • 1 US liquid quart = 32 US fluid ounces.
  • 32 US fluid ounces = 1 US liquid quart.
  • 2 US liquid quarts = 64 US fluid ounces.
  • 64 US ounces = 2 quarts.
  • 1 Imperial quart = 40 Imperial fluid ounces.
  • Formula: multiply the volume value by 32.

NOTE: A fluid ounce is not the same as an ounce for weight. When discussing a fluid ounce, do not confuse it with an ounce that measures weight.

There are three types of quarts namely: 1 – US Customary fluid and dry quarts and 2 – the Imperial quart. In the same way, there are two types of fluid ounces: 1 – US Customary fluid ounce and 2 – the Imperial fluid ounce. So, depending on what types of quarts and fluid ounces are used, the answer to the question of how many fluid ounces in a quart might be different.

Let’s break that down a bit.

  • 1 Ounce = 0.03125 Quarts
  • 16 Ounce = 0.50 Quarts
  • 32 Ounce = 1 Quarts
  • 64 Ounce = 2 Quarts
  • 96 Ounces = 3 Quarts.

If you find that confusing, we have further detailed the whole conversion process in the most understandable way for even a beginner. At the end of this guide, you’ll be well equipped with the right Quart to Fluids Ounce conversion knowledge and be able to answer how many ounces in a quart at any given time.

To help you understand how to convert ounces, first, let’s take a look at what these conversion terms are and how they differ.

What is an Ounce (oz)?

An ounce is a unit of measurement used in the Imperial system, mostly used in the United States. Ounces in general, can be used to measure either liquid or dried goods.

  • A fluid ounce (fl oz), is used to measure fluids (the volume of a liquid). Fluid ounces are mostly used in the United States and other countries who still uses the Imperial measuring system.

What is a Fluid Ounce (fl oz)?

A fluid ounce is an imperial and United States Customary measurement systems volume unit used to measure fluids (the volume of a liquid). 1 US fluid ounce = 0.03125 quart. 1 Imperial fluid ounce = 0.025 Imperial quart.

The symbol for fluid ounce is “fl oz”

  • 1 US fluid ounce = 0.03125 US fluid quart
  • 1 US fluid ounce = 0.0268552188 US dry quart
  • 1 Imperial fluid ounce = 0.025 Imperial quart

DID YOU KNOW? The word “ounce” was derived from the Latin word “uncia”. Uncia was a measuring unit that equaled one-twelfth of Libra or the Roman pound.

The ounce remains a standard unit in the United States, while the United Kingdom stopped using it as a legal unit of measure in 2000. Many British people still use it in everyday life on an informal basis.

What is a Quart (qt)?

A quart represented as (qt) (quarter of a gallon), is a measuring unit used in the Imperial system and United States to measure liquids and dried goods. It is a term used to tell how much a particular liquid weigh.

  • 1 US quart = 32 US fluid ounce (oz).
  • 1 Imperial quart = 40 Imperial fluid ounces (oz).

The best way to visualize and know how much a quart measures without all the fuss is to use a little container of milk. When you visit the grocery store near you, you will usually see a small container of milk, that little container of milk is equivalent to a quart which is equal to a gallon’s quarter.

Today, we have the metric system which is mostly used around the world, the Imperial system and the U.S. system of measurements.

How the Metric System of Measurement Differs

When there were still a few countries that used the Imperial system, the United States created their measuring system, referring to it as the “U.S. system”. This system only used one set of units for fluids and one set for dried goods.

The Imperial system, universally referred to as the British Imperial system even though the United Kingdom uses the metric system now, is almost exactly the same as the U.S. system but varies slightly in amounts.

How to convert fluid ounces to quarts?

1 Fluid ounce (oz) is equal to 0.03125 quart. To convert fluid ounces to quarts, multiply the fluid ounce value by 0.03125 or divide by 32

That is, to find out how many quarts there are in 16 fluid ounces, multiply 16 by 0.03125, which makes half quart in 16 fluid ounces.

fluid ounces to quarts formula:
quart = fluid ounce * 0.03125
quart = fluid ounce / 32

Common conversions from US fluid ounces to quarts (qts) are:

  • 8 oz = 1/4 quart
  • 16 oz = 1/2 quart
  • 24 oz = 3/4 quart
  • 32 oz = 1 quarts
  • 64 oz = 2 quarts

How to convert from US quarts to fluid ounces?

1 quart is equal to 32 fluid ounces (oz).
To convert quarts to fluid ounces, multiply the quart value by 32.

i.e., to find out how many fluid ounces there are in 2 quarts, multiply 32 by 2, that makes 64 fluid ounces in 2 quarts.

Quarts to fluid ounces formula: fluid ounce = quart * 32

Conversions from US liquid quarts (qt) to US fluid ounces (fl oz):

  • 1/8 quart = 4 fl oz
  • 1/4 quart = 8 fl oz
  • 1/2 quart = 16 fl oz
  • 1 quart = 32 fl oz
  • 1.5 quarts = 48 fl oz
  • 2 quarts = 64 fl oz
  • 2.5 quarts = 80 fl oz

How Many Fluid Ounces In 2 Quarts?

There are 64 fluid ounces in 2 quarts.

To arrive at an accurate answer and measurement of how many Fluid Ounces In 2 Quarts, do note that your result will vary, depending on the ingredient you are measuring. Your measurement will depend mostly on the density of the fluid.

Considering how many fluids ounce in a quart, the result will be exactly: 64 Fluid Ounce = 2 Fluid Quarts.

What about pints, cups, and gallons? How many ounces are there in them?

Having known that one quart is equal to 32 fluid ounces, how do we convert a quart into pints, cups, or gallons?

To know how many ounces are there in a pint, cup, and gallon, it is crucial we first understand what these things are and how they are measured. After which, I will provide you with the math that will enable you to a simple conversion and calculate how many tablespoons in an ounce and all.

One quart equals two pints, while one pint equals two cups. If we know that one cup equals eight fluid ounces, we can easily come back to the fact that one quart equals 32 fluid ounces.

In numbers.

  • 1 Quart = 2 Pints = 4 Cups = 32 fl. oz.
  • 1 Pint = 2 Cups = 16 fl. oz.
  • 1 Cup = 8 fl. oz.

Cooking is a form of science that also follows due procedures. The reason many foodies love foods food prepared by a Chef is because a good chef accurately measures the ingredients and how many ounces in a quart is required.

As an already established chef, a home cook or an aspiring chef, just as knowing common culinary terms is crucial, accurate measurement of ingredients is something to take seriously, because, if something goes wrong in the accuracy of the ingredients, then the recipe will likely be destroyed.

A good way to learn and master ingredient measurements is to practice often. Once you begin practicing often, you will know the precise amount of ingredients to use in making your favorite recipe, and even inventing new one yourself.
