Hello:

        Techically we are metric since all the english/usa units are now
defined in metric terms I.E. the inch is defined as 2.54 cm.
        I also belive that the feds require most drawings to have both
units on them. Our cars engines are now metric. we lost the old 250,  292
and 350 CID Chevys years ago. the big one was called a 5.7 litre for a
while before it pasted away. The only item left on a car that is metric I
think is the tires.
