About converting Fluid Ounces (US) to Quarts
Fluid Ounces (US) (fl oz) and Quarts (qt) are both units of volume, so converting between them is a single multiplication: multiply your Fluid Ounces (US) figure by 0.03125. Ten Fluid Ounces (US) comes to 0.3125 Quarts, and a hundred works out at 3.125 Quarts.
Rule of thumb: going from Fluid Ounces (US) to Quarts divides, so the figure always shrinks — it takes about 32 Fluid Ounces (US) to make a single Quart. If your answer came out bigger, you have the conversion the wrong way round.
What is a Fluid Ounce (US)?
A fluid ounce measures volume, not weight, despite sharing a name with the ounce on a kitchen scale — the two are related only loosely, through the weight of water. The US and imperial fluid ounces are different sizes, and counterintuitively the imperial one is the smaller, even though the imperial gallon is the bigger of the two: the imperial gallon divides into 160 fluid ounces, the US gallon into just 128. The gap is small enough to slip past a reader and large enough to matter, which makes it a reliable trap in cocktail recipes and drink can sizes.
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: a US shot of spirits is about one and a half fluid ounces, while a quart is the size of a standard carton of American milk.
