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.

What is a Litre? History, origin and usage

The litre was introduced in France in 1795 as a republican measure equal to one cubic decimetre, its name derived from the older French litron, in turn from Byzantine Greek (where it had been a unit of weight) via Late Medieval Latin. In 1901 the litre was redefined as the volume of one kilogram of pure water at maximum density, making it very slightly larger than a cubic decimetre. In 1964 that awkward definition was abandoned and the litre returned to being exactly one cubic decimetre.

The litre is the everyday metric unit of volume across most of the world: fuel sold at the pump, bottled water and soft drinks, milk, engine and cooking oil, and car engine capacity. It is the unit people reach for whenever a volume is larger than a kitchen spoonful but smaller than a tankful.

The litre is not an official SI unit but is accepted for use alongside it. Its symbol may be written as a capital L precisely because a lowercase l is easily mistaken for the digit 1 in many fonts.

How to use this US Quart to Litre converter

Type a number into the US Quart field and the equivalent in Litre 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 Litre field to convert the other way (litre to us quart). 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 qt = 0.9463529L), 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 quart-to-litre 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.
