# Surface Current Density Converter

Surface Current Density describes the amount of electric current flowing through a given surface area. It is a vector quantity, representing the current flow per unit area, and is denoted by the symbol "J".

Surface current density plays a crucial role in various applications, such as determining the magnetic field generated by electric currents, analyzing the behavior of conductive materials, and designing electrical systems. It is commonly expressed in units of Amperes per square meter (A/m²).

Surface current density can be expressed in different units depending on the system of measurement used. Below are the common units of surface current density and their conversion factors:

• Ampere per square meter (A/m²): The standard unit of surface current density, where one Ampere of current flows through one square meter of area.
Conversion factors: 1 A/m² = 1 A/m² (Base Unit)

• Ampere per square centimeter (A/cm²): This unit expresses surface current density in Amperes per square centimeter.
Conversion factors: 1 A/cm² = 10,000 A/m²

• Ampere per square inch (A/in²): Surface current density measured in Amperes per square inch.
Conversion factors: 1 A/in² ≈ 1,550 A/m²

• Ampere per square mil (A/mi²): Surface current density expressed in Amperes per square mil, where one mil is equal to one-thousandth of an inch.
Conversion factors: 1 A/mi² ≈ 1,550,003,100 A/m²

• Ampere per circular-mil (A/cmil): This unit represents surface current density in Amperes per circular mil, where a circular mil is the area of a circle with a diameter of one mil (0.001 inches).
Conversion factors: 1 A/cmil ≈ 1,973,525,242 A/m²

• Abampere per square centimeter (abA/cm²): The abampere is a unit of electromagnetic current in the CGS system. Abampere per square centimeter expresses surface current density in abamperes per square centimeter.
Conversion factors: 1 abA/cm² = 1 A/cm² = 100,000 A/m²
