Maybe to be consistent we should abandon our current currency denominations, which are basically metric, and go back to this set of denominations:
2 farthings = one half penny
2 half pennies = one penny
12 pennies = one shilling
5 shillings = one crown
4 crowns = one pound
21 shillings = one guinea
Much better than pennies, nickels, dimes, quarters, and on up which are only based on the numbers 1, 5, and 10.
Thank you Mr. Franklin and Mr Jefferson. Would that we’d listened to their council on all our metrics.

You think your being clever, but there are legitimate reasons to use systems based on other systems than decimals.
Let's say you have a pie, and you want to slice it fairly. You can easily cut into halves, quarters, sixths, eighths, or even twelvths, or sixteenths if you want to be chincy about it. Not nearly so easy to deliver 5 or 10 slices the same size.
Just because something makes something easier doesn't necessarily make it better for all applications.
Personally, I like the elegance of the design of the metric system, but there are common things that just aren't easily expressible in it. An inch or a foot is intuitive, a centimeter, much less so. Meters are ok because it's pretty close to a yard.
If you really want to go metric all the way it'll be a really expensive proposition. I'd hate to think how much waste and fraud the government could wrangle out of re-surveying the country. How many square meters (or kilometers if you'd rather) are in a Section of land?
