Quarts to fluid ounces (qt to fl oz) converter

What is a quarts to fluid ounces converter?

A quarts to fluid ounces converter is an online tool that turns a volume given in quarts into its equivalent in fluid ounces, and the other way around. Both units belong to the systems of customary measurement, but they appear in different settings: quarts are common for larger amounts of liquid such as milk, broth, or oil, while fluid ounces are used for smaller quantities like a serving of juice or a measured ingredient. The converter removes the mental arithmetic and lets you move between the two units instantly.

US, US dry, and UK quarts

The word “quart” covers three slightly different measures. The US liquid quart is the everyday quart used in American kitchens and on grocery shelves. The US dry quart is a larger unit reserved for dry goods such as berries or grain. The UK (imperial) quart is the British equivalent and is larger than its US liquid cousin. Because of these differences, one quart does not always contain the same number of fluid ounces:

• 1 US liquid quart = 32 US fluid ounces.
• 1 US dry quart ≈ 37.24 US fluid ounces.
• 1 UK quart = 40 UK fluid ounces.

How does the converter work?

Select the source quart type and the target fluid ounce type, then type a value. The converter multiplies your quart figure by the appropriate conversion factor and shows the result in fluid ounces. The reverse direction works the same way: enter a number of fluid ounces and the tool divides by the factor to return quarts. Because the calculation is bidirectional, you can edit either field and the other updates automatically.

Formula for conversion

The conversions rely on a fixed factor for each quart and fluid ounce pairing.

For US quarts to US fluid ounces: $\text{fl oz (US)} = \text{qt (US)} \times 32$

For US fluid ounces to US quarts: $\text{qt (US)} = \text{fl oz (US)} \div 32$

For UK quarts to UK fluid ounces: $\text{fl oz (UK)} = \text{qt (UK)} \times 40$

For US dry quarts to US fluid ounces: $\text{fl oz (US)} = \text{qt (US dry)} \times 37.24$

Conversion table

The table below lists common quart amounts and their fluid ounce equivalents for the three quart types.

Examples

Example 1: One US quart of milk

A recipe gives a quantity as 1 US quart of milk, but the measuring cup only shows fluid ounces. Multiply by 32:

$1 \text{ qt (US)} \times 32 = 32 \text{ fl oz (US)}$

Example 2: Two US quarts of stock

You are preparing a soup that calls for 2 US quarts of stock and want the figure in fluid ounces:

$2 \text{ qt (US)} \times 32 = 64 \text{ fl oz (US)}$

Example 3: Fluid ounces back to quarts

A bottle holds 32 US fluid ounces of liquid. To express that as quarts, divide by 32:

$32 \text{ fl oz (US)} \div 32 = 1 \text{ qt (US)}$

Example 4: A UK quart

For a British measurement of 1 UK quart, the imperial fluid ounce factor applies:

$1 \text{ qt (UK)} \times 40 = 40 \text{ fl oz (UK)}$

Notes

• Always match the quart type with the matching fluid ounce type. US quarts pair with US fluid ounces, and UK quarts pair with UK fluid ounces.
• The US dry quart is for dry volume and is not interchangeable with the liquid quart, so its fluid ounce equivalent differs.
• A US fluid ounce and a UK fluid ounce are not identical, which is one more reason to keep the systems separate.
• Using consistent units throughout a recipe or project avoids costly conversion mistakes.

Frequently asked questions

How many fluid ounces are in a quart?

A US liquid quart contains exactly 32 US fluid ounces. A UK quart contains 40 UK fluid ounces, and a US dry quart is about 37.24 US fluid ounces.

How many fluid ounces are in 2 US quarts?

Multiply 2 by 32 to get 64 US fluid ounces.

How do I convert fluid ounces back to quarts?

Divide the number of US fluid ounces by 32. For example, 32 US fluid ounces divided by 32 equals 1 US quart. If you mostly work in the reverse direction, our ounces to quarts converter is the quicker option.

Why is a UK quart not 32 fluid ounces?

The imperial quart is larger than the US liquid quart, and the imperial fluid ounce is slightly different from the US one. As a result, one UK quart equals 40 UK fluid ounces rather than 32.

Can the converter handle decimals and fractions of a quart?

Yes. You can enter any decimal value, such as 0.5 or 1.75 quarts, and the converter returns the precise fluid ounce result.

Is a US dry quart the same as a liquid quart?

No. The dry quart measures dry volume and is larger, equating to roughly 37.24 US fluid ounces, so it should not be used in place of the liquid quart.
