Gallons (gal): a US customary liquid-volume unit used for fuel, storage, and higher-capacity liquid measurement.

Cubic meters (m³): the SI structural volume unit used for larger capacities, bulk storage, and engineering calculations.

This route is useful when comparing structural and bulk volumes between cubic meters, cubic feet, and related liquid-capacity references in storage, airflow, and engineering work.

This conversion is purely multiplicative because both units reduce through liters or cubic meters using fixed volume definitions with no offset.
