At the risk of overposting today...
First of all, this person appears to think "metric" just means "any worldwide
standard" and he's
opposed to worldwide standards. What he means by the line that "there is no
metric electricity"
is that electricity has no global standards. You should probably let him know
that's not what
"metric" means.
I'd also point out that the voltages, currents, and frequencies used in various
equipment are
engineering decisions and are not standardized by the metric system itself. In
fact, even "metric
sizes" of construction equipment and such are not actually part of SI. SI is a
set of units to
use when stating the qualities of objects, not a set of standard sizes of
objects themselves.
Then I'd mention that all units for electricity are metric and always have
been, and in fact there
are no widely used non-metric units for voltage and current. I'd explain how
SI is a coherent
system and show exactly how volts and amps are defined in terms of the more
familiar meters,
kilograms, and seconds.
Finally, I'd close by mentioning that none of these predictions of doom have
come true for the
more than 200 nations that have gone metric.
But then again, I tend to be pretty wordy.
