Current density is the electric current per unit area of cross section. The current density vector is defined as a vector whose magnitude is the electric current per cross-sectional area at a given point in space, its direction being that of the motion of the charges at this point . In SI units, the electric current density is measured in amperes per square meter (A/m²). This Surface Current Density converter allows you to convert abampere/sq. centimeter (abA/cm²), ampere/circular mil (A/cmil), ampere/sq. centimeter (A/cm²), ampere/sq. inch (A/in²), ampere/sq. meter (A/m²), ampere/sq. mil (A/mil²), among other units related to Surface Current Density.
