How to Convert Milliliters to Gallons

To convert a measurement in milliliters to a measurement in gallons, multiply the volume by the following conversion ratio: 0.000264 gallons/milliliter.

Since one milliliter is equal to 0.000264 gallons, you can use this simple formula to convert:

gallons = milliliters × 0.000264

The volume in gallons is equal to the volume in milliliters multiplied by 0.000264.

For example, here's how to convert 5,000 milliliters to gallons using the formula above.

gallons = (5,000 mL × 0.000264) = 1.32086 gal

Milliliters and gallons are both units used to measure volume. Keep reading to learn more about each unit of measure.

What Is a Milliliter?

The milliliter is a unit of volume equal to 1 cubic centimeter, 1/1,000 of a liter, or about 0.061 cubic inches.[1]

The milliliter is an SI unit of volume in the metric system. In the metric system, "milli" is the prefix for thousandths, or 10-3. A milliliter is sometimes also referred to as a millilitre. Milliliters can be abbreviated as mL, and are also sometimes abbreviated as ml or mℓ. For example, 1 milliliter can be written as 1 mL, 1 ml, or 1 mℓ.

Since one milliliter is equivalent to one cubic centimeter, milliliters are sometimes expressed using the abbreviation for a cubic centimeter (cc) for things such as medical dosages or engine displacements.

What Is a Gallon?

The US liquid gallon is a unit of fluid volume equal to four quarts, eight pints, or sixteen cups.[1] The US liquid gallon should not be confused with the US dry gallon or the imperial gallon, which are different units of measure.

The gallon is a US customary unit of volume. Gallons can be abbreviated as gal; for example, 1 gallon can be written as 1 gal.
