What is a US Fluid Ounce? History, origin and usage
This entry is the same US fluid ounce (written fl oz), defined as one one-hundred-twenty-eighth of a US gallon and so anchored to the 231-cubic-inch Queen Anne wine gallon. The fluid ounce was historically the volume occupied by an ounce-weight of wine or water, which is how the volume and weight ounces came to share a name.
On US packaging fl oz is the standard way to state the contents of cans, bottles and cartons, from a 12 fl oz soda can to a 20 fl oz sports drink. Bartenders and pharmacists measure in fluid ounces too.
The American and British fluid ounces are close in size but not identical, so a 16 fl oz US pint and a 20 fl oz imperial pint are genuinely different volumes. The fluid ounce is a volume, not a weight, despite the shared word ounce.
What is a US Quart? History, origin and usage
This quart (written qt) is the US liquid quart, one fourth of the US gallon and a direct descendant of the Queen Anne wine gallon kept by the United States. The term comes through Old French from Latin quartus, simply meaning a quarter.
The qt is the practical kitchen-and-garage quart: a quart of buttermilk, a quart of engine oil, or a quart saucepan. It links the pint below it and the gallon above it in the US cooking ladder.
A US liquid quart is appreciably smaller than the imperial quart, so British and American recipes that call for a quart are not interchangeable. In the US, two pints make a quart and four quarts make a gallon.

How to use this US Fluid Ounce to US Quart converter
Type a number into the US Fluid Ounce field and the equivalent in US Quart appears instantly — there is no “convert” button to press and nothing is sent to a server, so it works offline once the page has loaded and is safe for any data. You can also type into the US Quart field to convert the other way (us quart to us fluid ounce). Use the swap control to flip the two units, and copy the result with a single click. Because the calculation runs in your browser with full floating-point precision, the converter is more exact than the rounded figures shown in the reference chart above — use the chart for quick look-ups and the tool for precise work.
Accuracy and method
Every figure on this page — the formula, the worked examples, the conversion chart and the “convert to other units” tables — is computed from a single verified conversion factor (1 fl oz = 0.03125qt), never copied from a hand-typed lookup table that could drift. That factor is derived from each unit’s definition in terms of a common base unit, and an automated check re-verifies all of the site’s factors on every update, so the numbers here stay correct over time. This matters for us fluid ounce-to-us quart conversions because a small rounding error in a published table compounds quickly at larger quantities; computing from the exact factor avoids that.
Watch the system: a <strong>US</strong> gallon, quart, pint and fluid ounce are <strong>not</strong> the same size as the <strong>imperial (UK)</strong> ones — a US gallon is 3.785 L while an imperial gallon is 4.546 L, and a US fluid ounce (29.57 mL) is slightly larger than an imperial fluid ounce (28.41 mL). The units on this page are labelled US or Imperial so the result is unambiguous.
