Fluid ounces to quarts (fl oz to qt) converter

What is a fluid ounces to quarts converter?

A fluid ounces to quarts converter is an online tool that helps you turn a volume given in fluid ounces into its equivalent in quarts, and the other way around. Both units belong to the customary volume systems used in the United States and the United Kingdom, so they show up constantly in cooking, bartending, and any situation where a recipe or container is labelled in one unit but you think in the other. Instead of remembering whether a quart holds 32 or 40 ounces, you type a number, pick the unit variants, and read off the answer.

US and UK fluid ounces and quarts

The catch with these units is that the US and the UK define them differently, and the US even keeps a separate “dry” quart for measuring produce. The most common pairings are:

• US fluid ounce (fl oz US) — about 29.5735 millilitres.
• UK fluid ounce (fl oz UK) — about 28.4131 millilitres.
• US quart (qt US) — exactly 32 US fluid ounces, roughly 0.946 litres.
• US dry quart (qt US dry) — about 1.101 litres, used for dry goods such as berries.
• UK (imperial) quart (qt UK) — exactly 40 UK fluid ounces, roughly 1.137 litres.

Because the relationships are exact within each system, 32 US fluid ounces always equal 1 US quart and 40 UK fluid ounces always equal 1 UK quart. Mixing systems (for example, dividing US ounces by a UK quart) is where most mistakes happen, which is exactly what the converter prevents.

How does the converter work?

The converter routes every value through a common base unit (the cubic metre) using each unit’s known size. When you enter a number of fluid ounces, it first finds that volume in the base unit, then expresses the result in the quart variant you selected — and vice versa when you edit the quart field. Selecting different unit options (US, UK, or US dry) simply swaps the factors used, so the same input can be read against any of the supported variants.

Formula for conversion

For US fluid ounces to US quarts (32 ounces per quart):

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

For US quarts to US fluid ounces:

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

For UK fluid ounces to UK quarts (40 ounces per quart):

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

For US fluid ounces to US dry quarts (about 37.24 ounces per dry quart):

$\text{qt (US dry)} = \text{fl oz (US)} \div 37.24$

Conversion table

The table below lists common fluid-ounce amounts and their equivalents in quarts for the most-used unit pairings.

Examples

Example 1: US fluid ounces to US quarts

Convert 32 US fluid ounces to US quarts. Since one US quart holds exactly 32 US fluid ounces:

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

Example 2: A larger US batch

A stockpot recipe calls for 64 US fluid ounces of broth. Converting to US quarts:

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

Example 3: US quarts back to fluid ounces

You have 1 US quart of milk and want the amount in fluid ounces:

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

Example 4: UK fluid ounces to UK quarts

In the imperial system one quart equals 40 fluid ounces, so 40 UK fluid ounces convert as:

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

Notes

• Always match the unit systems: divide US ounces by a US quart and UK ounces by a UK quart, never mix the two.
• The US dry quart is for dry goods only; use the liquid US quart for liquids.
• Within each system the figures are exact, so rounding only appears when you cross between US, UK, and dry variants.

Frequently asked questions

How many fluid ounces are in a quart?

A US quart contains exactly 32 US fluid ounces, while a UK (imperial) quart contains 40 UK fluid ounces. The difference comes from the separate definitions of the US and UK systems.

How do I convert fluid ounces to quarts?

Divide the number of fluid ounces by the ounces-per-quart factor: 32 for US units and 40 for UK units. For example, 64 US fluid ounces divided by 32 equals 2 US quarts.

How many quarts is 32 ounces?

32 US fluid ounces equal exactly 1 US quart. In UK units, 32 UK fluid ounces equal 0.8 UK quart.

Is a US quart the same as a UK quart?

No. A US quart is about 0.946 litres (32 US fluid ounces), and a UK quart is about 1.137 litres (40 UK fluid ounces), so the imperial quart is noticeably larger.

What is a US dry quart?

The US dry quart is a separate measure of about 1.101 litres used for dry produce such as berries and grains. It does not equal the liquid US quart, so the converter keeps it as its own option.

Can the converter handle decimals and small amounts?

Yes. You can enter any decimal value, such as 8 fluid ounces, and the converter returns the precise quart equivalent (8 US fl oz is 0.25 US quart).
