Understanding liquid measurements is an essential kitchen skill, whether you’re following recipes or simply need to know how much water fits in a container. A common question is: how many ounces are in a quart? Read on for a full guide to quarts, ounces, and converting between volume units.
Introduction to Quarts and Ounces
First, let’s review what quarts and ounces measure:
- A quart is a unit of volume equal to 32 fluid ounces[1]. It’s commonly used to measure liquids in cooking and recipes.
- An ounce can refer to either a unit of weight or volume. A fluid ounce measures the volume or capacity of liquids.
Since we want to know how many fluid ounces fit in a liquid quart, it’s important to note we are working with fluid ounces, not ounces of weight.
Volume Measurement Systems
The quart and fluid ounce are part of the US customary system of measurement used in the United States. But other places use metric or imperial measurements.
United States Customary
The US customary system uses quarts, gallons, fluid ounces, cups, pints, and more to measure liquid volume.
Imperial System
Used in the UK, imperial units like the imperial pint and gallon are slightly larger than US customary units.
Metric System
The metric system uses milliliters (mL) and liters (L) to measure volume. 1 liter = 1000 mL.
Converting Ounces to Quarts
Now we can get to the conversion:
Conversion Formula
There are 32 fluid ounces (fl oz) in 1 quart. To convert ounces to quarts:
Quarts = Ounces / 32
Divide the ounces by 32 to get the equivalent quarts.
For example, 64 fl oz / 32 = 2 quarts
Quick Conversion
As a handy guide:
- 16 fl oz = 0.5 quart
- 32 fl oz = 1 quart
- 64 fl oz = 2 quarts
And so on, since there are 32 fl oz per quart.
Conversion Table
Refer to this table when converting ounces to quarts:
| Fluid Ounces | Quarts |
|---|---|
| 8 fl oz | 0.25 qt |
| 16 fl oz | 0.5 qt |
| 24 fl oz | 0.75 qt |
| 32 fl oz | 1 qt |
| 40 fl oz | 1.25 qt |
Use the formula for conversions not listed.
Converting Quarts to Other Units
We can also convert quarts to cups, pints, gallons, and liters:
Cups
1 quart = 4 cups
To get cups, multiply quarts by 4.
Pints
1 quart = 2 pints
Multiply quarts by 2 to convert to pints.
Gallons
1 gallon = 4 quarts
Divide quarts by 4 to get gallons.
Liters
1 quart = 0.946 liters
Multiply quarts by 0.946 to convert to liters.
Accurate Measurements for Cooking
Converting between units helps ensure accuracy:
Weighing Ingredients
For precision, weigh ingredients like flour and sugar instead of using cup measurements, which can vary.
Using Units Consistently
Follow recipe units consistently. Don’t substitute cup for ounces measurements.
U.S. Customary Units
U.S. recipes typically use cups, tablespoons, and fluid ounces.
Metric Units
Metric recipes use milliliters, liters, and grams instead of quarts and ounces.
Conversion Tools
To make conversions easier, use:
- Online converters and calculators
- Apps like Volume for Android and iOS
- Conversion charts
These tools provide instant quart-to-ounce conversions and vice versa.
