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".

Most of the Construction-based Technical Documents (including the NEC), include SI values and "Standard Imperial".

Electrical Engineering is SI based, requiring Unit Conversions where applicable.
For me to determine wavelength, it is much easier to consider the value of "C" as 300,000 KM/S, as opposed to 186,000 Miles/S.

Illumination quantities - AKA "Lighting Levels", may be expressed as:
* Footcandles (Fc)
or
* Lux (Lx)
with a very simple conversion factor.

10 Fc = 100 Lx

To convert Lx to Fc:
Move the Decimal Point one space to the Left.

To convert Fc to Lx:
Move the Decimal Point one space to the Right.
