How Many Ounces in a Quart (Dry and Liquid Measurements)

Knowing how many ounces are in a quart is important for accurate cooking and baking. I answer that question and provide helpful cooking conversions and a free chart.

How many oz are in a quart? There are 32 fluid ounces in 1 quart. However, there are 37.23 ounces in 1 dry quart.

The relationship between ounces (oz) and quarts (qt) and the equipment used to measure them is a need-to-know for most cooks across American kitchens. That's because ounces and quarts are part of the imperial measurement system, the standard used in the United States.

Ounces and Quarts as Units of Measure

Ounces and quarts are both units of measure for both dry and wet ingredients. The fluid ounce metric is more commonly used within the U.S. standard measurement system.

Mathematical Conversion Formula

If you want to find out how many quarts are in a certain number of ounces, you would divide the number of ounces by 32.

quarts = fluid ounces ÷ 32
fluid ounces = quarts × 32

How would you use this formula in the kitchen?

For example, if you have a recipe calling for 64 ounces of milk and you want to determine how many quarts that is because the milk bottle you have on hand comes in a 2-quart container, you would set up this mathematical formula:

64 ounces ÷ 32 = 2 quarts

This equation would tell you that you can safely use your entire 2-quart bottle of milk in this recipe as it is the exact same as 64 ounces.

You can use this formula in reverse if you need to know the number of ounces in a quart.

Multiply the number of quarts by 32 to determine the equivalent in ounces.

2 quarts x 32 = 64 ounces

To help you out, here is a chart of conversions from ounces to quarts where I've done the math for you.

Definition of an Ounce (U.S. standard)

The term "ounce" used in the United States finds its origins in the Roman term "uncia," denoting 1/12 of a Roman copper bar. These bars were practical tools for measuring both the length of an inch and the weight of an ounce.

Despite its ancient Roman roots, the modern usage of the ounce in the United States can be traced back to British standards. For an American cook working in the kitchen, understanding the ounce is essential.

In cooking, particularly baking, precision in measurements is crucial. Here's where the ounce comes into play:

Fluid Ounces: A fluid ounce in the United States is 1/16th of an Imperial Pint and weighs roughly 1/16 of a pound, which translates to approximately 28.3 grams. When a recipe calls for fluid ounces, it's typically referring to the volume of a liquid ingredient, like water, milk, or oil.

Dry Ounces: When a recipe mentions ounces without specifying "fluid," it's referring to dry ounces. This is where things can get a bit tricky. A dry ounce is equal to 28.35 grams, just slightly more than a fluid ounce. So, when measuring flour, sugar, or other dry ingredients in ounces, it's crucial to use a kitchen scale for accuracy.

Metric Conversion: Within the metric system 1 ounce is approximately 28.35 grams.

Measuring in Cups: Many recipes provide measurements in cups, so it's useful to know that 1 cup is equivalent to 8 fluid ounces or 1 cup.

Note: Products sold in USA stores often have ingredients labeled in ounces. For example, a bag of flour might be labeled as 32 ounces. Understanding how to convert ounces allows you to alter the ingredient amounts you buy to scale up and down a recipe.

Definition of a Quart (U.S. standard)

Understanding the quart is essential for any American cook, as it is a common measurement used in recipes, especially when dealing with liquids. Here's everything you need to know about the quart in American kitchens:

Origin: The term "quart" has a clear etymology, derived from the Latin word "Quartus," meaning a fourth, and later from the French word "Quarte," representing a ¼ portion. This makes sense when you consider that in liquid measurements, a quart is precisely ¼ of a gallon.

Metric Measurement Variations: Not all quarts are created equal! In the United States, our quart is 32 fluid ounces. However, in the UK (and other countries adhering to the Imperial system), an English quart is slightly larger at 38.43 ounces. This difference stems from the fact that their gallon is 153.72 ounces, whereas ours is 128 ounces.

Practical Kitchen Knowledge:

Conversion: Understanding that a quart is 32 fluid ounces is crucial when following recipes. If a recipe calls for 1 quart of liquid, you know you'll need to measure out 32 fluid ounces.

Measuring Cups to Use: A standard measuring cup set often includes cups in sizes like ¼, ⅓, ½, and 1 cup. Knowing that 1 quart is equivalent to 4 cups simplifies things in the kitchen. So, if a recipe requires 1 quart of broth, for example, you can easily measure out 4 cups.

Bulk Buying: In grocery stores, you might find certain liquids like milk or broth packaged in quarts. Understanding that a quart is 32 fluid ounces helps you plan recipes and purchase the right amount of ingredients.

Recipes: Many soup recipes, sauces, and beverages are measured in quarts. For instance, a typical batch of soup might require 1 or 2 quarts of broth. Knowing this allows you to scale recipes up or down based on your needs.

Freezing: When meal prepping or preserving foods, understanding quart measurements is handy. Freezer bags or containers might be labeled in quarts, indicating how much each can hold. This makes it easier to portion out and store soups, sauces, or other liquids.

Fluid vs. Dry: While an ounce refers to both weight and volume, a quart refers to a liquid volume measurement.

Measuring Liquids, Semi-Liquids, Dry

While ounces are more commonly used to measure liquids, we also use ounces and quarts to measure dry ingredients such as coffee or chocolate chips, and semi-dry ingredients such as applesauce or yogurt.

Different Ways to Measure Quarts

Quarts are typically measured as the following units using the U.S. standard system where 1 quart equals 32 ounces:

Dry quarts (qt): Used for measuring dry ingredients such as rice, oats, and vegetables or fruit.

Fluid quarts (fl qt): A common measurement for liquids.

Different Ways to Measure Ounces

Ounces can be measured in two ways within the U.S. standard system where 1/32 of an ounce equals 1 quart:

Dry ounces (oz): Used for measuring dry ingredients like flour or sugar.

Fluid ounces (fl oz): Used for measuring liquids.

Here is a helpful chart for specific ingredients both dry and wet in both ounces and quarts.
