In a way, the US has been incorporating Metric "Terms" into standard values for quite some time; i.e.:
"Kilo" Volt-Amp,
"Mega" Watt,
"Milli" Amp,
"Deci" Bels,
"Micro" Farad.
In High School Physical Science, Metric values were used universally, without any requirements to convert results from SI Units to Imperial Units. This was a great way to "become Metric fluent".
...
Electrical Engineering is SI based, requiring Unit Conversions where applicable.

That's pretty much because electricity was discovered and developed after the Metric system was invented. Else we'd be dealing with Imperial measures of voltage, like "1 zapper = 2.54 volts" "We have 47 zappers on our powerlines in the USA". Thank heaven we don't have this silliness!
