Hi,
Ken said it all, "It's too easy to make a mistake" using Imperial.
With metric it is like making change---dollars, dimes, cents, etc. It is just automatic---especially if you had chemistry, physics, biology, etc. in college. All of that is done in metric. Heck the whole world is metric except US...that's a pun for us.
I multiply, add, divide, subtract any numbers I use and I do it in a fraction of a second in my head when I use metric---again, just like making change at the store.
With Imperial I get some number like 43/32 and I want to do something with it, I start going through coniptions like, "44/32 is close and I can divide that in my head. Divide by two and I get 11/16. Then I need to use that result with another number where I did the same thing and the error compounds. AND it has taken a bunch of time, whereas in metric the whole caboodle would have been done in a fraction of a second and would have been accurate.
Imperial measurements are one giant step backwards for mankind.
Auto mechanics, refrigerator repair men, hobbiests, etc. have to have two sets of open end wrenches, two sets of socket wrenches, two sets of accurate measuring devices, etc. Using Imperial is costing the people in this nation a gigantic amount of money...It is a crime!!!
The mom and pop garage is having a rough time surviving in these times. Doubling the cost of their tools is not helping. Think how much it costs the military in equipment costs, in communicating with the rest of the world, etc.
By now I assume you know which way I voted. My vote was a lie however. I said that I use both systems equally well. I don't. I am tremendously more accurate and efficient using metric. That is true even though I was born in the good ole USA.
Rant is over.
Enjoy,
Jim
