## How to Convert Gallons to Cubic Meters

To convert a gallon measurement to a cubic meter measurement, multiply the volume by the conversion ratio. One gallon is equal to 0.003785 cubic meters, so use this simple formula to convert:

The volume in cubic meters is equal to the gallons multiplied by 0.003785.

**For example,**here's how to convert 500 gallons to cubic meters using the formula above.

Gallons and cubic meters are both units used to measure volume. Keep reading to learn more about each unit of measure.

## Gallons

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.

## Cubic Meters

One cubic meter is equal to the volume of a cube with each edge measuring one meter.

The cubic meter, or cubic metre, is the SI derived unit for volume in the metric system. Cubic meters can be abbreviated as *m³*, and are also sometimes abbreviated as *cu m*, *CBM*, *cbm*, or *MTQ*. For example, 1 cubic meter can be written as 1 m³, 1 cu m, 1 CBM, 1 cbm, or 1 MTQ.
