A liter is a metric system measurement for volume. One kilogram of water is equal to one liter. One liter is equivalent to 1.0567 liquid US quarts, making a quart the slightly larger volume.

Two other quart measurements are commonly recognized: dry U.S. quart and U.K. quart. Both U.K. quarts and dry U.S. quarts are slightly smaller than a liter. One liter is equivalent to 0.90808 dry U.S. quarts and 0.87988 U.K. quarts.

Chefs and culinary students are two examples of groups that might need to convert between quarts and liters. Precise measurements are necessary for many recipes, so cooks must convert these volume measurements correctly.
