Explanation

US Gallons convert into imperial gallons inside the marine capacity family. Formula: Imp gal = US gal × 0.832674184629. The same fixed relationship is used in the calculator, common values, and mirror page so route checks stay aligned.

This is useful for marine navigation, onboard operations, sounding work, or vessel-capacity checks where nautical units and engineering units need to line up without changing the underlying reference model.

Method & Marine Basis

  • Method basis: fixed marine-capacity definitions used for tank, hold, and fueling calculations.
  • Applied factor: 1 US Gallon = 0.832674 Imperial Gallons.
  • Consistency rule: calculator output and common-value rows use the same fixed marine constants in both directions.
