Both quarts are a quarter of a gallon, and the gallons are different
The imperial quart is 1.1365225 liters and the US quart is 0.946352946 — the same 20% gap as the gallons they come from. A US quart is close enough to a liter for a recipe to swap them; an imperial quart is not, and treating one as the other overfills by about 14%.
NIST Handbook 44, Appendix C — general tables of units of measurement
What is a US quart?
Two pints, about 946 ml, and close enough to a liter that recipes swap them.
What is an imperial quart?
A quarter of an imperial gallon, 1.1365225 liters exactly. It is larger than a US quart by the same fifth that separates the two gallons.
How many imperial quarts are in a US quart?
