Metric holdouts! That's funny, right there, I guess because it's true. Ironically, we cling to the "English System" of measurement when everyone else, including the English, have gone metric. I personally don't understand the hullaballoo; the name of a given unit is completely irrelevant. 1/4th of a pound could be called 25% of a Fred, and it's still the same damned thing. The biggest argument I've heard is the old saw of "the metric system is all in tenths." So what? So are decimal inches. You can decimalise any unit of measurement, as you can fractionalise any unit of measurement. I understand people having a hard time with fractions; I know a lot of people who have a hard time with, say, welding. Anyone who argues that one or the other system is "easier" to manipulate will have a big job of convincing me of that. Now, getting rid of pounds, shillings, and pence in favor of decimalisation? THAT made sense.
EDIT: Forgot to add, my wife is a scientist and I am an aircraft mechanic specializing in Canadair Regional Jets (a fine quality Canadian product, BTW). We are both fluent in metric due to our jobs, so it doesn't matter to us, anyway.
