CT, I suprised that you still use the trade size instead of the "Metric Designator" used in the 2002 code book.
16 = 1/2", 21 = 3/4", 27 = 1", 35 = 1 1/4", 41 = 1 1/2", 53 = 2", 63 = 2 1/2", 78 = 3", 103 = 4", 129 = 5", and 155 for 6".

"Hey Jimmy, as your 1st job as an electrician's helper, go to the truck and get 30.48 meters of #16 conduit!"

Is anybody really using meteric measurements?
