How it works
The calculator multiplies quarts by the litres in the kind you pick. A US liquid quart is 3.785411784 L divided by 4, which is 0.9464 L.
Four US quarts are one US gallon, 3.7854 L. Two litres are 2.1134 US qt.
A UK imperial quart is 4.54609 L divided by 4, which is 1.1365 L. You pick it from the list.
This is not a US dry quart and not a whole gallon. A gallon is on a separate page.
You may enter zero; the result is then also zero. The calculator does not accept negative numbers.
Millilitres and fluid ounces are on the millilitres page.
Formula
L = qt × (3.785411784 / 4) or qt × (4.54609 / 4)
These are the same US and UK gallon constants as on the litres and gallons page.
