That's good - within an inch of their lives

So much for the metric conversion - ROFLOL

We use kms, kilos, kpa etc but we still build in imperial measure and the prints are in mm's how many mm's is a 2x4 ? or a 6" sched 160 pipe?

It's so ridiculous that it's laughable.....

There are two ways to measure octane, that yield indices about 10 points apart. In the American we use the average of the two, in Europe the highest of the two.

So for a given brand of gasoline:

RON = 85
MON = 95

European rating (MON) = 95
US/Canada rating (AKI) = (85+95)/2 = 90

To confuse things further, the US and Europe use different horsepower definitions.

So my Z4 makes 300 hp in the US on 93 octane, and would make 306 hp on 98 octane if I took it back to Europe!

Yes is it not fantastic, in Europe they develop that much HP (PS) that they run there cars upside down as you can see here by the photo I took last year in the Porsche Museum in Stuttgart Germany
