For those who cook on a daily basis, you all know that it is much more difficult than it seems. Most recipe failures have to do with incorrect measuring – especially when trying to convert imperial measuring units to metric measuring units. If you’re in need of knowing how many oz in a quart, we have the answer. 1 quart is equal to 32 oz. By the end of this article, you’ll be well equipped to answer how many ounces in a quart.
An ounce is a unit of measurement used in the Imperial system, mostly used in the United States. Ounces can be used to measure either liquid or dried goods.
A quart is also a measuring unit used in the Imperial system that can also be used to measure liquids and dried goods.
Now, this might seem very confusing. You get the metric system, which is used mostly around the world. You also get the Imperial system as well as the U.S. system.
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, now mostly 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.
What are these measuring units?
When discussing a fluid ounce, you should not confuse it with an ounce that measures weight. A fluid ounce, as the name states, is used to measure fluids (the volume of a liquid). Fluid ounces are mostly used in the United States or some countries that still use the Imperial measuring system.
Many other measuring units are used when measuring volume. Cups and milliliters, for example, is a metric measuring unit that is used most often during cooking.
Other Imperial and U.S. measuring units for liquids include quarts, pints and gallons. Each of these is often used in recipes and not knowing the conversions could potentially lead to some kitchen-disasters.
A quart is defined as a quarter of a gallon – this will help you later in calculating conversions to a quart liquid.
Just as with many fluids to dry conversions, they are not very accurate as different items have different volume to mass ratios. However, just like grams and milliliters are often converted, so can fluid ounces to dry quarts. But like we said, it is important to make sure the item you are converting has a similar volume and mass amount – otherwise, the conversion will not work.
Converting fluid ounces to U.S. Quart (liquid)
A fluid ounce is a unit of volume, meaning it is used to measure the volume of a liquid. Some liquids, like water or milk, have similar mass amounts than their volume amounts.
One fluid ounce (Imperial system) equals 28.4 milliliters (Metric system).
One fluid ounce (U.S. system) equals 29.6 milliliters (Metric system).
As you can see, the U.S. systems’ fluid ounce contains slightly more than the Imperial systems’ does when comparing the two. This might seem small, and it may be, but within certain recipes, it could make a massive difference in the outcome of the product.
A quart is another measuring unit that can be used to measure both wet and dry ingredients, but it should be noted that the conversion from liquid to weight only works if the ingredient has the same amount of volume to mass.
One fluid quart equals 32 fluid ounces (U.S. system).
One fluid quart equals 33.31 fluid ounces (Imperial system)
This means that one U.S. liquid quart equals 946 milliliters while one Imperial liquid quart equals 1136 milliliters.
One dry quart (U.S. system) equals 37.24 liquid ounces (U.S. system)
One dry quart (U.S. system) equals 38.76 liquid ounces (Imperial system)
Other measuring units
Even though we now know how many fluid ounces one quart contains, there are still many other conversions that can be done.
Knowing different types of conversions can help you a lot during cooking and in other aspects of your life too.
Pints and cups
We already know that one fluid quart equals 32 fluid ounces. Keep this in mind for later.
One fluid quart equals 2 pints.
To calculate the number of fluid ounces in one pint, simply divide 32 (fl. oz.) by two. Remember, if one quart equals 32 fluid ounces and 2 pints, half the amount of pint will be equal to half the amount of fluid ounces.
Two pints equals 4 cups (1000 milliliters).
4 cups equals 32 fluid ounces.
32 fluid ounces equals one fluid quart.
Do you see how it is useful to know all your conversions! You can easily calculate how many ounces are in a cup and how many cups are in any number of pints.
One gallon is equal to 4 quarts. It does however make more sense to say that one quart is a fourth of a gallon.
That is how the name “quart” originated, as a quarter of a gallon.
Thus to calculate the number of fluid ounces in a quart, simply multiply 1 quarts’ worth of ounces (32) by four and you will get 128 fluid ounces.
1 gallon equals 128 fluid ounces (32 fluid ounces x 4)
Using the previous conversions, you can also calculate the amount of pints and cups in gallons.
Because one quart equals two pints, if you multiply two pints by four, you will see that 8 pints equals 1 gallon.
The same goes for calculating cups; two pints equal 4 cups of liquid, thus when you multiply the four cups by four, you will get 16 cups that are equal to 1 gallon.

Hopefully, you can now see that if you know your conversions, you never again have to google in order to calculate them. Convert ounces to quarts to pints to gallons and even to cups – they are all so easy!
Even by just knowing a few, you will be able to use them and calculate exactly the amount you need. They are so useful and you do not have to shy away from foreign recipes anymore.
