Convert between milliliters, liters, cubic meters, fluid ounces, cups, pints and gallons using US customary definitions.

1 US gallon is exactly 3.785411784 L, and a 12 fl oz can holds about 354.88 mL, usually printed as 355 mL. A 500 mL bottle is about 16.91 fl oz, and 1 L is about 4.22675284 US cups.
Every volume passes through liters using exact definitions: a US gallon is 3.785411784 L, a US pint is one eighth of that at 473.176473 mL, and a US fluid ounce is 29.5735295625 mL. One cubic meter is exactly 1,000 liters, which is handy for tanks and ponds.
The cup, pint, fluid ounce and gallon here are US units. The imperial gallon used in the United Kingdom is 4.54609 L, about 20% larger, and the imperial pint is 568.26 mL, so a UK pint holds more than a US one. Check which system a label, recipe or fuel price uses before converting.

So a 12 fl oz can holds about 354.88 mL, usually printed as 355 mL, and a 500 mL bottle is about 16.91 fl oz. A 2 L bottle is about 0.5283441 US gallons. One cubic meter is exactly 1,000 liters, which is useful for tanks and ponds.
The units in this converter are US units. The imperial gallon used in the United Kingdom is 4.54609 L, about 20% larger, and the imperial pint is 568.26 mL, so a UK pint of milk or beer holds more than a US pint. Imperial fluid ounces are also slightly smaller than US ones. Check which system a label, recipe or fuel price uses before converting; mixing the two is one of the most common sources of error.
A US cup here is 236.5882365 mL, so 1 L is about 4.22675284 cups. Nutrition labels in the United States round a cup to 240 mL, many other countries use a 250 mL metric cup, and Japan uses a 200 mL cup, so recipes from different countries can disagree by more than 20%. For spoons and small kitchen amounts, use the Cooking Converter. Volume does not tell you weight: a cup of water and a cup of flour have very different masses.

1 pint (US) → mL | 473.176473 |
2 L → gallon (US) | 0.5283441 |
No, it measures volume. How much a fluid ounce weighs depends entirely on what is in it, so a fluid ounce of oil and a fluid ounce of honey have different masses. For grams, ounces and pounds of an ingredient, use the Weight Converter instead.
The cup here is the US cup of 236.5882365 mL, so 1 L is about 4.22675284 cups. Nutrition labels in the United States round a cup to 240 mL, many countries use a 250 mL metric cup and Japan uses a 200 mL cup, so recipes from different countries can disagree by more than 20%.

A 2 L bottle is about 0.5283441 US gallons, and a 12 fl oz can is about 354.88235475 mL. For larger containers, work in cubic meters: 1 m³ is exactly 1,000 L, so a tank quoted in cubic meters converts to liters by moving the decimal point three places.
