As a person under the Imperial unit of measurement system I'll agree that Metric is probably better and I would love to have a base 10 system of measurement. Make everything simple and whatnot.
However, you must also agree that to change our system of measurement would be absurdly costly and to accuse us of being inferior for keeping with such a system is childish.
Don't have to change it all abruptly, do you? Have both systems for a while, start teaching Metric in school and sooner or later you'll be bi-systemal. Then you can stop using Imperial all together.
There's something neat and tidy about metric. I mean, the fact that 1 centimeter cubed of water is 1 milliliter is 1 gram? That's just awesome.
Favorite unit though? Angstroms are pretty neat, largely because of the funny little circle on the A for its symbol.
It's not funny!
On a serious note, though: My favourite unit would be either Celsius, Joule, or Curie, all because I like how they sound. And also Kelvin because of how ridiculously great and impractical it is at the same time. And Rankine because of
it's creators absurdly awesome beard.
I don't see any fun in measuring stuff though.
And while I have a lot of bad jokes about measuring "stuff" bubbling inside me at the moment, I think I'll abstain from posting any of them as I do not want to push this thread further into what I believe Vector has called "boy's locker room humour" territory.
