Gallon

[cbong]

When we say measuremets are in Gallon, do we mean UK Gallon or US Gallon?

[augi_ow]

i would think is US... cause UK seldom use gallon... correct me if i'm wrong... UK usually use litres... =)

[cbong]

That's wat I thot. But ...

UK Gallon or Imperial Gallon = 4.55 ltr
US Gallon = 3.79 ltr

Quite significant difference.

3WPG is based on US Gallons.

For local websites and forums, most use US gallon probably because of WPG.

For other information, look at where the info comes from. A lot of the prominent English language planted tank websites are in the USA.
