Method and precision
Conversions use a factor of 3.785411784 litres per us gallon, applied exactly and rounded to 3 decimal places for display only. The converter above uses the unrounded factor.
What to watch for
A US gallon is 3.785 litres; an imperial gallon is 4.546 litres. They share a name and differ by about twenty per cent, so a fluid capacity quoted in "gallons" without a country is ambiguous and worth confirming before you fill anything.
