Hi .
I'd say 'it depends'.
Miles are sure handy. We've gotten used to those very nicely. 60 is
pretty fast. 100 is a very fast even number.
120 km/hr does not automatically mean much to most of us 'Murakins.'

and psi ...man are those nicer than kilopascals or whatever they are !!!

OTOH  15, 17, and 19 mm make far more sense in wrench sizes than say
31/64's  does.

So it depends.

ok ....trivia quiz...
The origin of the dimension 'one foot' comes from the length of the
king's foot I believe.
What is the origin, or definition of, the meter ?
Where did they derive that dimension from ?
