How Many Oz In A Quart: Handy Guide For Precise Measuring


I have already talked about how cooking appears to be simple only to those who have never tried it. We who cook every day know that it is not as easy as it seems.

How Many Oz in a Quart

I do not know a single person, be it an amateur or a professional, who has not failed at cooking at least once in a lifetime. Many of those failures have to do with measuring the ingredients the wrong way, or at least not precisely enough.

Even the best recipes can be puzzling if the measurements are not provided so that you can understand them. For this reason, I have decided to write handy guides for precise measuring that will help you succeed no matter who wrote the recipe. Ounces or milliliters, Imperial or US system of measurement – it will be all the same to you!

Some historical background

First, I will say a few words about the ounce, and I know that many Europeans who use the metric system will be grateful for that. The ounce (abbreviated oz.) represents a unit of volume, mass, or weight. It is used in the majority of British-derived systems of measurements, including the US and the UK Imperial system.

Interesting Fact: The etymology of the word ounce leads straight to the Latin language. Namely, this word 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. Of course, many British people still use it in everyday life, and we can thus say that it is still used only on an informal basis.

In the US measurement system, ounces in a quart can be calculated in two units – U.S quart (liquid) or U.S quart (dry):

1. How many fluid ounces in a U.S Quart (Liquid)?

A fluid ounce (fl. oz. or oz. fl.) is a unit of volume. In the Imperial system, one fluid ounce equals approximately 28.4 ml: while in the U.S system, the fluid ounce stands for about 29.6 ml of liquid.

  • Imperial system: 1 fl. oz. = 28.4 ml
  • U.S system: 1 fl. oz. = 29.6 ml

Many people just say an “ounce” when, in reality, they think about the fluid ounce, especially in bartending or even cooking.

One quart (liquid) has approximately 32 U.S fluid ounces, while in the imperial system, one quart equals 33.306969 (33.31) fluid ounces.

  • 1 U.S fluid ounce = 1/32 U.S quart liquid.
  • 1 U.S quart liquid = 33.31 Imperial fluid ounces.

We can put it the other way around too:

  • 1 Quart (qt) = 32 fl. oz. U.S
  • 1 Quart (qt) = 33.31 fl. oz. Imp.

2. How many fluid ounces in a U.S Quart (Dry)?

When it comes to U.S quart (dry), it contains 37.236711 U.S fluid ounces or 38.757564 Imperial fluid ounces. We can thus approximately set the value of the U.S quart (Dry) as follows :

  • 1 Quart Dry = 37.24 U.S. fluid ounces.
  • 1 Quart Dry = 38.76 Imperial fluid ounces.

What about pints, cups, and gallons?

We now know that one quart is equal to 32 fluid ounces, but how can this help us if we need to convert a quart into pints, cups, or gallons. I will provide you with the math that will enable you to do so in a simple way.

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.

Let me break it down for you:

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

What is a gallon?

A gallon is a unit of measurements that is equal to four quarts. It is better to say, though, that a quart is one-fourth of a gallon, as that is how it got the name in the first place (“quart” is an abbreviation of the word “quarter”).

If quart equals 32 fluid ounces and gallon has four quarts, we can multiply 32 by four and get how many fluid ounces there are in a gallon. Let’s do that:

  • 1 gallon = 32 fl. oz. multiplied by 4 = 128 fl. Oz.

We can also use the same math to calculate how many pints or cups there are in one gallon of liquid:

  • 1 gallon = 2 pints multiplied by 4 = 8 pints
  • 1 gallon = 4 cups multiplied by 4 = 16 cups

Interesting Fact: 3/4 gallon = 2 quarts = 64 ounces which equals eight 8-ounce glasses – the amount of water we need to drink on a daily basis! 🙂

Do you want to find out how much a quart of water weighs?

It might be interesting to find out how much a quart of water actually weighs. You never know – you might need that information one day too!

  • One quart of water weighs somewhere around 2 pounds.

It is not the exact number as the weight of water depends on the temperature as well, but it is definitely a safe assumption and the amount you can use in case of emergency.

How did we come up with this?

  • One gallon of water weighs around 8 pounds (8.3 on average) at a warm temperature. We have learned that there are 4 quarts in each gallon, and thus each quart weighs a little bit over 2 pounds. Simple math! 🙂

Step by step, you will become a master of precise measuring and be able to convert any given measure in any recipe in the world. Sounds great, doesn’t it? 🙂
