How It Works
The US cup is defined as exactly 236.5882365 mL, which is half a US liquid pint or one-sixteenth of a US gallon. To convert liters to cups, the calculator divides 1000 mL (one liter) by 236.5882365 mL per cup, producing the conversion factor of approximately 4.22675 cups per liter. Your liter value is then multiplied by this factor. The result is returned to four decimal places. Note that this uses the US customary cup — the metric cup used in some countries is 250 mL, giving a different factor of exactly 4 cups per liter, and the imperial cup used historically in Canada and the UK was 284 mL.
Examples
One Liter of Water
Converting 1 liter to US cups.
Result: 1 L equals approximately 4.2268 cups.
Large Pot of Soup
Converting 3 liters of soup to cups.
Result: 3 L equals approximately 12.68 cups.
Half-Liter Cream Carton
A 500 mL (0.5 L) carton of heavy cream for a baking recipe.

Frequently Asked Questions
How many cups are in a liter?
There are approximately 4.22675 US cups in one liter. A quick mental shortcut is to think of a liter as just over four cups, which is accurate enough for most cooking purposes. For precise baking, use the exact value.
Does this use US cups or metric cups?
This calculator uses the US customary cup, defined as exactly 236.5882365 mL. The metric cup used in Australia, Canada, and some other countries is 250 mL, which gives exactly 4 metric cups per liter. If your recipe is from one of those countries, use the metric cup value instead.
Can I use this for cooking?
Yes — this calculator is ideal for adapting European or Australian metric recipes to US cup measurements. Just enter the liter amount from the recipe and read the equivalent cup quantity. For very small amounts like 0.05 L or less, measuring in milliliters directly with a kitchen scale tends to be more accurate.
