A liter is bigger than a quart. Not by a landslide, but by a noticeable margin. One liter equals about 1.0567 quarts. Think of it this way: a liter is a quart that’s been drinking a little extra.
So if you pour a liter of milk into a quart container, you’ll have a splash left over. That splash is exactly why recipes can be tricky when you swap one for the other.
Let’s break it down, just for fun.
A U.S. quart is exactly 32 fluid ounces. A liter is roughly 33.8 fluid ounces. See? Less than two ounces of difference. But in baking or mixing drinks, those two ounces can turn a cake into a pancake.
Side comment: If you’re making a big batch of soup, don’t stress. But if you’re making a delicate sauce? Maybe grab a measuring cup.
