"Electric Current Density" is a measure of the density of flow of electric charge; it is the electric current per unit area of cross section. Electric current density is a vector-valued quantity. Electric current, $I$, through a surface $S$ is defined as $I = \int_S J \cdot e_n dA$, where $e_ndA$ is the vector surface element.
Applicable units are those of quantitykind:ElectricCurrentDensity

$J = \rho v$, where $\rho$ is electric current density and $v$ is volume.
