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.
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.
To put both in perspective: the UK gallon began as the volume of ten pounds of water, while a quart is the size of a standard carton of American milk.
