what is the deference between us gallon and IMP gallon ??
can any one compare with litre?

and when anyone say tank size is .... this means us or imp??/

i think we all just use whatever is used in our country so theres probably a mix when were talking about it.

1IMP gallon = 1.2 US gallons as a rough guide as a british gallon is 4.5 litres and an american gallon is 3.8 litres.

Yeah, British gallons are like an American gallon plus a quart. What I do know from brewing is that 5 American gallons is almost exactly 19 litres.

thank u

thank you friends
but would you please tell which one we use ??

when you say for example 1 table of x medicine for 10 gallons?
what did you mean
or when sb say I have a 55 gallons mean which one means 209 lit or 247.5 ittre
do you know why i am asking this because I heard for each discus you need 10 gallons of water. ( 45 or 38 which one?)
