US cups to litres multiplies by 0.236588 (1 US customary cup = 236.588 mL). Four cups are 0.946 L, just under a litre; a recipe calling for 6 cups of stock needs 1.42 L. Cup standards vary — the US legal cup is 240 mL (0.24 L) and the metric cup is 250 mL (0.25 L) — so a litre is about 4.23 US customary cups but exactly 4 metric cups. For anything that must rise or set, weigh in grams instead of trusting cup-to-litre arithmetic.
Batch-cooking recipes scaled from a handful of cups up to a stockpot-sized multiple often get re-expressed in litres for a commercial kitchen's metric equipment. 4 cups (a quart) is 0.946 L; 8 cups is 1.893 L; 16 cups (a gallon) is 3.785 L. When a home recipe gets scaled tenfold for catering, converting the cup total to litres upfront avoids the compounding rounding errors that come from multiplying a cup-based recipe by ten and then converting each ingredient separately.

A standard US recipe cup of water is about 237 mL. Most US recipes call for cups; weighing in grams is more reliable. In liters, that gives you: 1 cup = 0.236588 L, 10 cup = 2.36588 L, 100 cup = 23.6588 L.
The US legal cup, as used in nutrition labels, equals exactly 240 mL; the US customary cup, used in recipes, equals 236.5882365 mL (half a US liquid pint, or 8 US fluid ounces). Convertitive uses the customary value, which matches how most US cookbooks specify quantities. UK and Australian metric cups are 250 mL — yet another small but consequential difference.
The liter (L) is a metric unit of volume defined as exactly one cubic decimeter (1 dm³). Although not an SI base unit (the SI unit of volume is the cubic meter), it is the most common metric volume unit in everyday life, used for beverages, fuel, and chemistry. One liter of pure water at 4 °C weighs almost exactly one kilogram.
