Full API documentation

Explanation

Formula: US Gallons = Cubic Meter × 264.172052. 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.

Cubic Meters (m³): the SI volume unit used for hold capacity, tank volume, and larger marine storage calculations.

US Gallons (US gal): a US customary liquid-volume unit used for fuel, tanks, and onboard capacity references in US-based contexts.

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.

Method & Marine Basis

Method basis: fixed marine-capacity definitions used for tank, hold, and fueling calculations.
Applied factor: 1 Cubic Meter = 264.172052 US Gallons.
Consistency rule: calculator output and common-value rows use the same fixed marine constants in both directions.
