Liter to Cup Converter
What Is a Liter?
The liter (L) is a metric unit of volume equal to 1,000 milliliters or 1 cubic decimeter. It is the global standard for measuring liquids in cooking, commerce, and science. Most countries outside the US use liters for everyday liquid measurement, including recipes.
What Is a Cup?
The US customary cup (c) is a unit of volume equal to 8 fluid ounces, 16 tablespoons, or approximately 236.588 milliliters. It is the primary liquid and dry ingredient measure in American cooking and baking. Note: the metric cup (250 mL) and the imperial cup (284 mL) differ from the US cup.
Liters to Cups Formula
The conversion factor is:
US cups = liters × 4.22675
Derived from: 1 US cup = 236.588 mL, so 1 L = 1,000 ÷ 236.588 ≈ 4.22675 cups.
Worked Example
Convert 2 liters of water to US cups:
- Multiply: 2 × 4.22675 = 8.453 cups
So 2 liters ≈ 8½ cups — roughly a half gallon.
Quick Estimation
1 liter ≈ 4¼ cups. Multiply by 4, then add a quarter cup. Example: 3 L ≈ 12 + ¾ = 12¾ cups (exact: 12.68). For cooking precision, 240 mL ≈ 1 cup is the common kitchen shortcut.

Which Is Bigger: Liter or Cup?
A liter is about 4.2 times larger than a US cup. One liter = 1,000 mL, while one US cup = 237 mL. So a liter fills just over 4 cups. The metric cup (250 mL) fits exactly 4 per liter, but the US cup (237 mL) is slightly smaller.
When You Need This Conversion
- Adapting international recipes: European and Asian recipes measure liquids in liters or milliliters. A recipe calling for 1.5 L of broth = about 6⅓ US cups.
- Nutrition labels: Imported products show serving sizes in mL/L. A 1-liter carton of milk = about 4¼ US cups (34 fl oz).
- Hydration tracking: The common "2 liters per day" recommendation equals about 8.5 cups — close to the traditional "8 cups a day" guideline.
Frequently Asked Questions
How many cups are in a liter?
4.22675 US cups. For cooking, round to 4¼ cups. If using metric cups (250 mL), the answer is exactly 4.
Is 4 cups the same as 1 liter?
Close but not exact. 4 US cups = 946 mL, which is about 54 mL short of a liter. 4 metric cups (250 mL each) = exactly 1 liter.
How many cups are in 2 liters of water?
2 liters = 8.45 US cups. This is why drinking "2 liters a day" is roughly equivalent to the traditional "8 glasses a day" guideline.
What is the difference between a US cup and a metric cup?
A US cup = 236.588 mL. A metric cup = 250 mL — about 5.7% larger. Australian, New Zealand, and Canadian recipes typically use metric cups. Always check which cup a recipe assumes.
How do I convert cups to liters?
Divide the number of US cups by 4.22675, or multiply by 0.2366. Example: 10 cups × 0.2366 = 2.366 liters.
