Why this conversion matters in chemistry
Recipes use cups; chemistry uses liters. The US customary cup is exactly 236.588 mL by definition (eight US fluid ounces), so four cups land at 0.946 L — close to a liter but not equal to one. The 5.4% gap between four cups and a liter is the slack that household measurements can absorb but a quantitative calculation cannot. Food chemistry and educational demonstrations are where the conversion comes up most: a recipe in cups has to land in liters before any concentration or yield calculation can proceed cleanly.
Formula
Worked Examples
One US cup, the household-recipe standard — close to but not exactly 250 mL.
About one quart — close to but 5.4% short of a liter, which is the gap behind every "a liter is roughly a quart" approximation.
A large household-volume reference — about the volume of a stockpot or a small carboy.
Two cups, close to half a liter — useful when adapting a household recipe to a 500 mL volumetric flask.
