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.

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 = 0.03125 qt), 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.

Sources

• NIST Special Publication 811 — Guide for the Use of the SI — publishes the exact metric equivalents of the customary units. The inch, foot, yard and mile are defined exactly in metres by the 1959 international yard-and-pound agreement, so every imperial figure on this page is exact, not rounded.
• BIPM — The International System of Units (SI Brochure) — the defining document for the SI, published by the International Bureau of Weights and Measures. It fixes the base unit that this conversion resolves to, which is why the factor here can be exact rather than approximate.

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.
