Exact RatioAbout Ampere per Square Meter (A/m²)
The SI coherent derived unit of electric current density, defined as one ampere of electric current flowing through a cross-sectional area of one square meter (J = dI / dA).
History: Formulated by André-Marie Ampère and James Clerk Maxwell; fundamental to the microscopic Ohm’s law (J = σE) and Ampère-Maxwell law (∇×B = μ₀J + μ₀ε₀ ∂E/∂t).
Common Uses: Conductor ampacity ratings, electric motor coil winding current loading, electrochemical cell electrode current densities.
About Ampere per Square Centimeter (A/cm²)
A metric unit of current density equal to 10,000 A/m².
History: The standard laboratory engineering unit for electroplating, fuel cells, and power semiconductors.
Common Uses: Hydrogen PEM fuel cell polarization curves (operating ranges 0.5–2.0 A/cm²), industrial chlor-alkali electrolysis cells.
