Liters to US Gallons

Snapshot

1 Liter equals 0.264172 US Gallons. Conversion Encyclopedia uses the same fixed conversion basis across the calculator, common values, and reverse page for this page.

Reference basis: This result uses fixed marine-capacity definitions for tanks, holds, and onboard volume checks.
Example: For 2 Liters, the result equals 0.528344 US Gallons.
Use the reverse page if you need the opposite direction with the same basis.

Explanation

Formula: US Gallons = Liter × 0.264172. 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.

Liters (L): a metric liquid-volume unit used for smaller tank, fuel, and onboard capacity references.

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 Liter = 0.264172 US Gallons.
Consistency rule: calculator output and common-value rows use the same fixed marine constants in both directions.
