Is Electric Field ALWAYS measured in N/C?

[Antonius]

Is it OK to write it in something like N/pC? or N/microC?

Is time always measured in seconds? Or can we sometimes write nanoseconds or picoseconds?

Measurements are just measurements. We use whatever scale we need to simplify the problem.

I suspect in practice, the electric field is usually measured in V/m or some derivative such as V/cm or μV/m. (Yes, I know V/m = N/C.)

Thank you :)

Almost always in class we use N/C. :)

Almost always in class we use N/C.

That's probably because the electric field is usually taught (in terms of force and charge) before the electric potential, in introductory courses.

N/C = V/m, but the latter is used more often. At least, as much as I paid attention in physics last semester :D
