dont forget - UK gallons are 4.54 liters and US gallons ate 3.8 liters 
I have lived in both and its confusing!
but the conversion is pretty much right - except if you want the UK gallons multiply by 6.28 instead of multiplying by 7.5
OR like someone said - go use the online calculators but be careful about the difference in liters per gallon - not so much a biggie for sizing a pump, but needed for meds etc.
