umm, nope British Gallon = 4.546090L US Gallon = 3.785412 https://en.wikipedia.org/wiki/Gallon https://en.wikipedia.org/wiki/Gallon Though I had forgotten that the US used a different one. So my maths is off above. Thanks for pointing that out! Using the US Gallon: £1.21 per liter == $1.61 per liter == $6.09 per Gallon.
