What is a Quart?
A quart is a quarter of a gallon, which is exactly where the name comes from — the Latin for a fourth part. Because the American and imperial gallons are different sizes, so are their quarts: the imperial quart is the larger by roughly a fifth, a discrepancy that quietly ruins recipes and technical specs copied across the Atlantic without checking. In the United States the quart is a supermarket fixture — milk, cream, motor oil and paint are all sold in them. Britain, having gone metric on the shelf, has largely dropped it and kept only the pint.
What is an UK Gallon?
The imperial gallon is defined as exactly 4.54609 liters, but it started as something far more tangible: the volume occupied by ten pounds of water. Britain adopted it in the 1824 reform that swept away a tangle of older gallons — wine, ale and corn measures each had their own — and much of the Commonwealth followed. It is noticeably larger than the US gallon that America retained, so a British car advertised at 50 miles per gallon is genuinely more frugal than an American one quoting the same number. It survives today mainly in fuel-economy figures, since UK forecourts sell petrol by the liter.
To put both in perspective: a quart is the size of a standard carton of American milk, while the UK gallon began as the volume of ten pounds of water.
