How it works
Every unit is converted through litres using exact definitions: a millilitre is 0.001 L, a cubic metre is 1,000 L, a US liquid gallon is 231 cubic inches or exactly 3.785411784 L, and an imperial (UK) gallon is exactly 4.54609 L. So 1 L is 1 ÷ 3.785411784 ≈ 0.26417 US gallons, and 10 US gallons is about 37.85 L.
The definitions come from NIST Special Publication 811 (US gallon), the UK Weights and Measures Act 1985 (imperial gallon) and the BIPM SI Brochure (litre and cubic metre).
The two gallons are different sizes: the imperial gallon is about 20 % larger than the US gallon. Check which one a label or a fuel price uses.
