How Many OZ in 2 Quarts? Liquid Measurement Conversion
The Short Answer
2 quarts equals 64 fluid ounces. That's it. That's the conversion you came for.
If you're cooking and your recipe calls for 2 quarts but your measuring cup only shows ounces, you need 64 oz. Simple math: 1 quart = 32 oz, so double it.
Why This Conversion Matters
Most liquid measurements in the US use quarts, pints, and cups. But many tools—blenders, pitchers, some recipes—mark their units in ounces. You need to know how to swap between them or you'll end up guessing.
Wrong guesses mean ruined recipes. Too much liquid in soup. Too little in a sauce. The math exists for a reason—use it.
US vs. Imperial: The Catch
Here's where people mess up. US fluid ounces and Imperial fluid ounces are not the same size.
- 1 US fluid ounce = 29.57 mL
- 1 Imperial fluid ounce = 28.41 mL
That difference compounds. For 2 quarts:
- US measurement: 64 US fluid ounces (1,892.71 mL)
- Imperial measurement: 64 Imperial fluid ounces (1,818.43 mL)
The gap is about 74 mL—roughly a quarter cup. Most US recipes use US measurements. If you're following a British recipe, double-check which system it uses.
Quick Conversion Table
| Quarts | Fluid Ounces (US) | Fluid Ounces (Imperial) | Milliliters |
|---|---|---|---|
| ½ quart | 16 oz | 16 oz | 473 mL |
| 1 quart | 32 oz | 32 oz | 946 mL |
| 2 quarts | 64 oz | 64 oz | 1,893 mL |
| 4 quarts | 128 oz | 128 oz | 3,785 mL |
How to Measure 2 Quarts in Ounces
Grab a liquid measuring cup. Most have ounce markings on the side.
- Pour liquid into the cup until you hit the 64 oz mark
- Check at eye level—the surface should be flat, not curved
- No 64 oz cup? Use two 32 oz measurements
- Still too big? Four 16 oz portions work too
For dry ingredients, ounces measure weight. For liquids, ounces measure volume. Don't mix these up or your recipe will be off.
Common Kitchen Mistakes
Confusing weight and volume: 64 oz of water weighs about 4 pounds. 64 oz of honey weighs more. A cup is always a cup, but a pound isn't always a pound of liquid.
Using dry measuring cups for liquids: They aren't designed for it. You'll spill. Use a clear liquid measuring cup instead.
Ignoring temperature: Liquids expand when warm. A quart of cold water is slightly less volume than a quart of hot water. For precise baking, this matters.
When You Don't Need Precision
Making a big batch of lemonade? Estimate. The difference between 63 and 65 ounces won't ruin your drink.
Pressure canning? That difference matters. Follow the recipe exactly or risk spoilage.
Bottom Line
2 quarts = 64 fluid ounces. Remember that and you're set for most cooking and kitchen work. The US system uses this conversion. If your recipe comes from outside the US, verify the measurement system first.
