DO look up what physicists mean when they use the word 'dimension'
in the context of unit systems. It is not your fantasy meaning,

both wrong, the strength is actually the Intensity, which is directly
related to space and time. The coulomb is related to space and the
second to time. These physicists are unable to translate units!

Apparently you mean 'current density'.
But that is something else, because that quantity contains 'space' and
measures the current through an area-unit.
The usual interpretation of 'current' ignores that quantity and sums up
the current over the entire wire in question, while the term current
density does not.
"entire wire"?? you must be kidding, this usenet user doesn't know what a
current is in physics. But that's also related to time, said above, and you
cannot "ignore" anything, once directly not related, but connected. Just as
a translation of pig from engilsh to swine in gearmon. It's the same pig,
you eat alot. How many pigs did you eat along your journey?
Well, actually I mean:
the Ampere addresses the current in a conductor, which is usually a wire.
There Ampere does not say, whether the wire is thick or thin, or whether or not the current distributes evenly within the wire.
If you have a wire with a current of 1 A, you don't mean the distribution of the current within the conductor, but the sum of all small partial currents within that wire.
