Stupid beginner question: is MTr/mm² really the right thing to be looking at? Shouldn't it be more like mm²/MTr ? This feels kind of like these weird "miles per gallon" units, when "gallons per mile" is much more useful...

200 million transistors per square millimeter. Gallons per mile only makes sense when you are talking about dragsters.

  gallons per hundred miles make much more sense than that. incidentally, this is the measure rest of the world is advertising, except usually in liters per 100km. there's a good reason for this: comparisons linear instead of inversely proportional. 6l/100km is 50% better than 9l/100km. 30mpg vs 20mpg is... not as simple.

  Gallons per hundred miles would be more useful. I guess it's a matter of approach. Europeans are traveling familiar, constant distances and worry about fuel cost. Americans just fill up their tank and worry how far they can go :)

    If I buy 2 gallons of gas, and my car gets 30 mpg, then I can go 60 miles. Doesn't seem that hard to me. Need the other way around? I need to go 100 miles. At 30 miles per gallon, that's a little over 3 gallons. This is simple mental math.

Researchers at Duke University say that drivers find it easier to select the right answer when efficiency is expressed as gallons per 100 miles (g/100m). So 18 mpg (or 5.5 g/100m) versus 28 mpg (3.6 g/100m)--an increase of 10 mpg--represents a 52 percent reduction in consumption.

What’s the argument for either? They are, of course, equivalent… might as well pick the one where bigger=better.
