I was raised using both systems (Metric and Imperial).
Each system has its pros and cons.
I know that water freezes at 0 and boils at 100 (C).
I know that studs must be 16 inches on center and a standard sheet of drywall is 4 feet by 8 feet.
I know my weight in lbs, my height in feet and inches.
If you do any sort of contracting in Canada, you use imperial, because its much easier to say "Cut the stud to 7'5 1/4"" rather than "Cut the stud to 2.26695meters".
And if you *do* use metric for contracting, you end up using up to 3 decimal places constantly, because 2.266 is a lot different than 2.260.
The systems have their places. Saying that one is better than the other is very subjective and context sensitive.
