The 39th Root of 92
I continue to be baffled by the arcane units in the US.This uses a measure on the completely wrong abstraction level.An accidental production process now defines a wire unit instead the end result the consumer/engineer/technician wants to know (mm^2 or inch^2 oh no no it's pica^2 ?).There must be some sociological phenomenon going on that keeps the US from adopting modern units. Maybe can't admit a shortcoming and fix it?
