Gallons
 

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?)
