To find the current density I need to multiply (nLA)e

do i need to convert 10.0 protons cm^-3 to 10000000m^-3 because i tried that and it didnt work????

thanks.

If you really want to use the units km/s for speed then you should use (km)^-3 for your density and expect an anwser in units Amps/(km)^2. Alternatively you could convert the speed to cm/s (leaving density in (cm)^-3) and that would get you an answer in units Amps/(cm)^2.
