How Many Ounces in 2 Quarts? Conversion Guide

The Short Answer

2 quarts equals 64 fluid ounces. That's it. That's the number you came for.

But if you're measuring anything other than water, the actual weight in ounces will be different. Volume measurements don't automatically equal weight. A quart of honey weighs way more than a quart of water.

Most people asking this question are cooking, baking, or doing some kind of container sizing for liquids.

US vs Imperial: Why Your Answer Might Be Wrong

There are two measurement systems that both use the term "quart." This trips people up constantly.

• US liquid quart = 32 fluid ounces
• Imperial quart (UK) = 40 fluid ounces

So 2 US quarts = 64 fl oz. 2 Imperial quarts = 80 fl oz.

If you're in the United States, you're using the US system. If you're in the UK, Canada, or Australia, you might be dealing with Imperial measurements. Most international recipes specify which system they're using.

When in doubt, check where the recipe originated. American recipes use US measurements. British recipes use Imperial.

Quick Conversion Table

How to Convert Quarts to Ounces

The math is dead simple. Multiply quarts by 32 for US fluid ounces.

Example: 2 × 32 = 64

For Imperial: multiply by 38.4

Example: 2 × 38.4 = 76.8

Keep in mind this only works for liquid measurements. Dry ingredients use a completely different system based on weight, not volume.

What About Dry Quarts?

There's also a US dry quart, used for measuring things like flour, rice, or produce. It's slightly larger than a liquid quart.

• 1 US dry quart = 37.24 fluid ounces
• 2 US dry quarts = 74.48 fluid ounces

This is why baking recipes that use weight measurements are more reliable than those using volume. A "cup" of flour can vary wildly depending on how you scoop it.

Practical Examples

Here's where you'll actually use this conversion:

Cooking and Recipes

Many soup, stew, or drink recipes call for quarts. If your measuring cup only shows ounces, you now know to use 64 oz for 2 quarts.

Container Sizing

Buying pitchers, pitchers, or storage containers? Manufacturers often list capacity in quarts. Now you know 2 quarts fits 64 ounces of liquid.

Dilution Ratios

Some concentrates or syrups dilute with water at a 1:4 or 1:5 ratio. Knowing your base measurement in ounces helps you scale recipes correctly.

Why Precision Matters

For water and water-based liquids, 1 fluid ounce weighs almost exactly 1 ounce by weight. This is a happy coincidence that makes the math easy.

But for anything thick, dense, or sugary, the volume-to-weight relationship breaks down completely. A quart of maple syrup weighs more than a quart of water. A quart of olive oil weighs less.

If you're baking, use a kitchen scale. If you're cooking, measuring cups work fine for most applications.

The Bottom Line

2 quarts = 64 fluid ounces (US system). Remember this number and you can handle most measurement situations that come up in the kitchen.

Just don't try to weigh a quart of honey and expect it to be exactly 64 ounces. It won't be. Physics doesn't work that way.
