SwitchExplanation
Formula: Cubic Meters = US Gallon × 0.003785. Why: tank and hold-capacity units are tied to fixed volume definitions, so the route normalizes through one volumetric basis before applying the target unit.
US Gallons (US gal): a US customary liquid-volume unit used for fuel, tanks, and onboard capacity references in US-based contexts.
Cubic Meters (m³): the SI volume unit used for hold capacity, tank volume, and larger marine storage calculations.
This route is useful when translating tank, hold, and onboard liquid-capacity values across metric and gallon-based systems for storage, fueling, and vessel operations.
This conversion is purely multiplicative because both units reduce through one fixed marine reference basis for the active family, with no offset.
