Convert volume between litres, US customary cooking units and cubic measures via the cubic metre.
result = value × (from→m³) ÷ (to→m³)
It converts convert volume between litres, us customary cooking units and cubic measures via the cubic metre by first normalising your value to the SI base unit (cubic metre) and then scaling to your chosen target unit. This hub-and-spoke approach guarantees every unit pair is internally consistent.
1 US gallon to litres: 1 × 0.003785412 = 0.003785412 m³, then ÷ 0.001 = 3.785 L.
No. A US gallon is 3.785 L while an Imperial (UK) gallon is 4.546 L. This converter uses US customary units, so a UK recipe pint will be larger than the US pint used here.

Conversions are exact ratios where the units are defined exactly (most SI and imperial units) and best-available constants otherwise. Extremely large or small magnitudes are shown in general (g) format; round-tripping through the base unit may introduce tiny floating-point differences in the final decimal places.
