MODERATORS
In a number of instances where there is not a standard in place already it is not uncommon to see metric measurements mixed with imperial or US customary measurements.
I’m not in any way shape or form claiming that ALL of it is mixed.
However what does actually happen is the a unit of measure might be mixed with a customary one and then that becomes the defacto measurement, you may see wire resistance shown as a mix of Ohms/1000ft.
I am not getting into an argument about the merits of metric, I’m on board, I am with you. That doesn’t mean there aren’t some silly oddballs.
Is their an imperial equivalent to ohm?
It might be the case that imperial resistance is ohm the same as metric. Metric uses ohm as it's constituent with base units of metric, but imperial doesn't abide by rules like that.
If you had to make a imperial equivalent to resistance, it would be a fraction of the resistance of the monarchs finger.
There's no non metric electrical units except ohms/1000 ft or cross section dimensions, and AWG (and MCM kilo circular mils kcmils) versus mm^2
Why US uses awg with reverse scale instead of diameter is insane
formula: D(AWG) = 0.005·92^((36-AWG)/39) inch
