Liters to mL Converter

Convert liters to milliliters, or milliliters to liters, with US cups, fluid ounces, gallons and cubic centimeters.

Results

ItemValue
1 liter is exactly 1,000 milliliters, and 1 mL is the same as 1 cubic centimeter (cc). Cups, fluid ounces and gallons are US customary measures.

Quick Answer

Multiply liters by 1,000 to get milliliters: 0.5 L is 500 mL, 1.5 L is 1,500 mL and 2 L is 2,000 mL. To turn milliliters into liters, divide by 1,000 (move the decimal point three places left): 750 mL is 0.75 L and 330 mL is 0.33 L. A liter is about 4.23 US cups or 33.8 US fluid ounces.

How This Liters to mL Converter Works

Drink bottles, medicine, engine oil, recipes and lab work use liters and milliliters, sometimes on the same label. Choose the direction, enter the amount and press Calculate. The converter gives milliliters (or liters), plus US cups, fluid ounces, gallons and cubic centimeters so you can compare with US measures.

Quick explanation: 1 liter = 1,000 milliliters.

  • L to mL: multiply by 1,000 (move the decimal point 3 places right).
  • mL to L: divide by 1,000 (move it 3 places left).
  • cc: 1 mL = 1 cm³ = 1 cc.

How to Use the Liters to mL Converter

  1. Choose liters to milliliters or milliliters to liters.
  2. Enter the amount.
  3. Press Calculate.
  4. Read the converted volume, plus cups, fluid ounces, gallons and cubic centimeters.

Liters to mL Formulas

  • Definition: 1 liter (L) = 1,000 milliliters (mL) = 1 cubic decimeter
  • Milliliters from liters: mL = L × 1,000
  • Liters from milliliters: L = mL ÷ 1,000
  • Cubic centimeters: 1 mL = 1 cm³
  • US measures: 1 L = 4.2268 cups = 33.814 fl oz = 0.26417 gal

Key Terms

  • Liter (L): 1,000 mL, one cubic decimeter.
  • Milliliter (mL): one thousandth of a liter.
  • Cubic centimeter (cc): the same volume as 1 mL.
  • Centiliter (cL): 10 mL, used on drink labels.
  • Deciliter (dL): 100 mL, used in some lab results.

Worked Example

A recipe needs 0.35 L of stock. How many milliliters is that, and how many US cups?

  • 0.35 × 1,000 = 350 mL
  • In US cups: 350 ÷ 236.59 = 1.479 cups, about 1 1/2 cups
  • In fluid ounces: 350 ÷ 29.57 = 11.83 fl oz

Going the other way, a 591 mL soda bottle is 591 ÷ 1,000 = 0.591 L, which is the 20 fl oz bottle sold in the US.

Real-Life Examples

  • Drinks: a 1.5 L bottle is 1,500 mL, or 50.7 fl oz.
  • Medicine: 0.005 L is 5 mL, one teaspoon.
  • Cars: 4.5 L of oil is 4,500 mL, about 4.76 quarts.
  • Hydration: 2 L of water is 2,000 mL, about 8.5 cups.

Liter vs Milliliter

  • Liter (L): 1,000 mL, about a quart.
  • Milliliter (mL): one thousandth of a liter, about 20 drops.
  • Use: liters for bottles and tanks, milliliters for doses and recipes.

Liters, Milliliters and Cubic Centimeters

The liter is a metric unit of volume equal to one cubic decimeter, a cube 10 cm on each side. A milliliter is one thousandth of that, a cube 1 cm on each side, which is why doctors and mechanics also call it a cubic centimeter (cc). A 50 cc scooter engine has a displacement of 50 mL; a 5 cc syringe holds 5 mL.

Because liters and milliliters differ by exactly 1,000, conversions never need rounding: just move the decimal point. Mistakes usually come from mixing in other units. Some countries also use the centiliter (cL, 10 mL) and deciliter (dL, 100 mL), especially on drinks and lab results: 33 cL is 330 mL and 1 dL is 100 mL. A capital L is used for liters so it is not confused with the number 1. Measuring jugs in most kitchens show both milliliters and cups, so you can check a converted amount by eye.

Common Mistakes to Avoid

  • Moving the decimal the wrong way. Liters become a bigger number in mL.
  • Using 100 instead of 1,000. 100 mL is a deciliter.
  • Reading 1.5 L as 150 mL. It is 1,500 mL.
  • Mixing mL and mg. mL is volume; mg is weight.
  • Confusing L and 1. Write liters with a capital L.
