Liters to Cups Converter

Convert liters to cups with our free liters to cups converter — or flip it and turn cups back into liters. One liter equals 4.22675 US cups, so a 2-liter bottle holds about 8.45 cups, and this page converts either way instantly.

How it works

Liters and cups both measure volume, but they come from different systems. The liter belongs to the metric system and is used in most of the world: one liter is the volume of a cube ten centimetres on each side, or exactly 1,000 milliliters. The cup belongs to the customary system used for cooking: one US cup is 236.588 milliliters, which is 8 fluid ounces. Because the two units are different sizes, converting between them is a simple multiplication by a fixed factor.

The conversion factor is 4.22675 US cups per liter:

To convert liters to cups, multiply by 4.22675. To go the other way, divide cups by 4.22675 — or multiply by 0.236588, which gives the same answer. The converter above does both directions: type the amount, pick the direction, and use the swap button to flip it. For a quick estimate in the kitchen, remember that one liter is a little more than four cups, so rounding to four cups per liter is fine for rough work — but for baking, where small errors change the result, use the exact factor.

The one thing to watch out for is that not every "cup" is the same cup. The US customary cup used in this converter is 236.588 mL. The metric cup used in many other countries is 250 mL, which makes one liter exactly four metric cups. There is also an older imperial cup of about 284 mL, now rarely used. If a recipe comes from a metric cookbook, its cups are probably 250 mL, and converting with the US factor will overfill by about 6 percent per cup — enough to matter in a cake. Check which cup the recipe means before you convert, and use the matching factor.

This conversion comes up constantly in the kitchen. Recipes cross borders freely now: a soup recipe from a metric site gives stock in liters, while the measuring cups in the drawer are marked in cups; a drinks recipe gives lemonade in liters, while the punch bowl is measured in cups. It also matters for drinks and meal prep: a 2-liter bottle of soda is 8.45 cups, so it fills about eight standard cups with a little left over, and a daily water target of 2 liters is about 8.45 cups, not eight exactly.

For dry ingredients the story is different, and this converter does not cover it. A cup of flour does not weigh the same as a cup of sugar, so volume-to-weight conversions for dry goods need a density for each ingredient — the same idea as converting milligrams to milliliters. Liters to cups only works for liquids and for volume-to-volume amounts, where the substance does not change the answer.

Worked example

A cook is making lemonade for a party. The recipe makes 2 liters, and the punch bowl is marked in cups, so she wants to know how many cups 2 liters is.

Step 1: Write down the amount — 2 liters.
Step 2: Use the conversion factor — 1 liter = 4.22675 US cups.
Step 3: Multiply — 2 × 4.22675 = 8.4535.
Step 4: Round to two decimal places — 8.45 cups.

That is the exact result this converter gives for 2 liters: 8.45 cups. Going the other way, 4 cups converts to liters by dividing 4 ÷ 4.22675, which gives 0.946, or about 0.95 liters — just short of a full liter, which is why a recipe calling for a liter needs a little more than four cups.
