Volume is the category where the US and imperial systems diverge most damagingly. Gallons, quarts, pints and fluid ounces all exist in two sizes that differ by up to 20%, and nothing in the name warns you which one a figure uses. Recipes, fuel economy figures and container capacities all cross borders regularly, so it is worth checking which system a source is using before converting rather than after.
quarts to liters formula
To go the other way, use us quart = liter ÷ 0.94635295.
About these units
A quart is a quarter of a gallon, so it inherits the US and imperial split: 946 millilitres against 1,137. The name is simply a contraction of "quarter".
A litre is exactly one cubic decimetre, or 1,000 cubic centimetres. One litre of water weighs almost exactly one kilogram, which is not a coincidence.
US Quart is also written quarts and qts. Liter is also written litre, litres, liters and ltr.
