How the conversion works

The relationship is m³ = gal × 0.003785411784. Both units measure volume, so the conversion is a fixed factor that never changes. The figure is exact rather than approximate: since the international yard and pound agreement of 1959, an inch is defined as exactly 25.4 millimetres and a pound as exactly 0.45359237 kilograms, and every other imperial and US customary unit here is derived from those two.

US gallon: US liquid gallon. The imperial gallon is about 20% larger.
