This converter turns UK gallons into liters. One UK gallon is 4.54609 liters. It is free, needs no sign-up and runs in your browser, so nothing you enter is uploaded.

One UK gallon is 4,546.09 ml. These are imperial (UK) units: the imperial gallon is exactly 4.54609 L and a UK pint is an eighth of it, 568.26125 ml. The US gallon is smaller, 3.785411784 L, so a US figure and a UK figure that share a name are not interchangeable.
One UK (imperial) gallon is exactly 4.54609 liters, so a 10 UK gallon tank holds 45.4609 L. Petrol in the UK is sold by the liter but car economy is still quoted in UK miles per gallon, which is why this conversion comes up on fuel receipts and spec sheets.
If a figure comes from a US source it uses the smaller US gallon of 3.785 L, so 10 US gallons is only 37.8541 L. Use the US gallons page for those.
