How to Convert Cubic Meters to Gallons

To convert a measurement in cubic meters to a measurement in gallons, multiply the volume by the following conversion ratio: 264.172052 gallons/cubic meter.

Since one cubic meter is equal to 264.172052 gallons, you can use this simple formula to convert:

gallons = cubic meters × 264.172052

The volume in gallons is equal to the volume in cubic meters multiplied by 264.172052.

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

gallons = (5 m³ × 264.172052) = 1,320.860262 gal
