Gallons vs. Gallons -- further

["Simon Matthews" <simon_atwork@hotmail.com>]

Given my calucation in the earlier email, we have:
1. a UK gallon is 20% larger than a US gallon and
2. a US gallon is 17% smaller than a UK gallon.

Not the 25%/20% figures given earlier. As I mentioned, it is a common 
misconception that the fluid oz measures are the same.

Check it out! But use the real figure for a US gallon in litres: 3.785, not 
3.6.
