Ampere Per Square Meter (A/m²) is a unit in the category of Electric current density. It is also known as ampere/square meter, ampere/square metre, ampere per square metre, amperes per square meter, amperes per square metre. This unit is commonly used in the SI unit system. Ampere Per Square Meter (A/m²) has a dimension of L^-2I where L is length, and I is electric current. This unit is the standard SI unit in this category.

Note that the seven base dimensions are M (Mass), L (Length), T (Time), Q (Temperature), N (Aamount of Substance), I (Electric Current), and J (Luminous Intensity).

Other units in the category of Electric current density include Abampere Per Square Centimeter (aA/cm²), Ampere Per Square Centimeter (A/cm²), Ampere Per Square Decimeter (A/dm²), Ampere Per Square Foot (A/ft²), Ampere Per Square Inch (A/in²), Coulomb Per Second Per Square Meter (C/s-m²), and Milliampere Per Square Centimeter (mA/cm²).
