How to convert milliliters to gallons
1 milliliter = 0.0002641721 gallons. To convert milliliters to gallons, divide by 3,785.411784 (or multiply by 0.0002641721). A milliliter is one thousandth of a liter, the same as one cubic centimeter. A US liquid gallon is 231 cubic inches, exactly 3.785411784 L.
Worked examples
- 500 milliliters = 0.132086 gal (500 ÷ 3,785.4118)
- 1,000 milliliters = 0.264172 gal (1,000 ÷ 3,785.4118)
- 3,785 milliliters = 0.999891 gal (3,785 ÷ 3,785.4118)
Where this conversion comes up
Milliliters are used for medicine doses, drinks, perfume and recipes outside the US; gallons for gasoline, milk, paint and fish tanks in the US. A US gallon is 3,785.41 ml, so a 2-liter bottle (2,000 ml) is 0.53 gal and 500 ml is 0.13 gal. For imperial gallons divide by 4,546 instead.
Quick estimate
Divide by 3,800 (0.4% low).
Common mistakes
- Multiplying instead of dividing. A gallon is larger than a milliliter, so the number of gallons must come out smaller: 500 milliliters = 0.132086 gal.
- Using the imperial (UK) unit. This page uses US measures. An imperial gallon is 4.546 L (20% more than a US gallon), an imperial pint 568 ml and an imperial fluid ounce 28.41 ml.
- Rounding too early. Keep the full factor until the last step; rounding 0.000264 to 0.00026 first puts large values noticeably off.
