I'm not sure how it is anymore, but during my days in school we learned standard measurements first and metric just a year or two after that -- hypothetically along with the conversions.

The strange thing is that, even though I've learned many things that way (i.e. first A, then B too), I have never really got a good grasp on metric measurements. But I have bad spacial estimation skills, anyway.

I know the conversions. I have a solid concept of how long a centimeter, meter, and kilometer are. But if you tell me "I am xxx cm. tall," I have no mental image of that. (Sorry Nagoyankee!) However, chances are that if you tell me "I am xx in. tall," I will still have to devide it by twelve to form that mental image!

Ultimately, I think America should maintain its system, but we need to be willing and able to do the conversions for ourselves.

Now I'll go practice my conversions! Don't want to be a hypocrite.
