metric tools - not so dumb question?

Being a Quebecer (French-Canadian), this is my territory (North-american
person speaking an european language).

Relation between MPG (in US gallons) and liters/100 km is very easy:

Just use my pre-calculated formulae:
 
235/mpg = L/100km
or the inverse (obviously): 235 (divided by) L/100km = MPG (US)

Example: 10 L/100km is 23.5 MPG (US)

For you Brits (and non-metric-yet fellow Canadians) just add 20% to the MPG
(US) figure and you'll get the MPG (imperial).

So, 10 L/100km is 28.2 MPG (imperial).


Amusing fact: when I was looking into the mileage (or kilometreage...)
numbers for the 2004 Volkswagen models, I found out many confusing facts:

- US EPA and Canadian EPA-equivalent (Transports-Canada) don't use the same
standards for their calculations. 
- www.VW.ca in English used to convert US-EPA figures to metric units
- www.VW.ca in French used to convert Transport-Canada figures to Imperial
gallon MPG units. 
- www.VW.com for USA showed EPA US-gallon figures.

Result?  All 3 sites were showing different numbers, all true!

Babel tower you said?
