I'd be perfectly content to use metric, and end up using both systems regularly but it's not as if it's up to me what the whole country uses.

We don't need to dumb things down to a level for idiots to be able to do the math. -- Offworld checks no longer accepted!

Measure the current to be sure. Oh I can convert. Trouble is, IME a single gauge can cover a range of CSAs. Plus it's pointlessly and wastefully time consuming. Graham

Maybe because we are??? Why are there three distinct classes of units in physics? (eventhough SI units are somewhat universal). Cross sectional area and diameter are basic parameters that engineers understand and taught to convert between any system of units. Difference between an engineer and an hack?

Mostly inertia, of course. On the other hand, the AWG scale is right simple to use to swag the nominal wire resistance, given that it's a log scale and starting with AWG 10 = 1 ohm/1000 feet (yeah, "feet" but ...). -- Rich Webb Norfolk, VA |
