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 Milliampere per Square Centimeter (mA/cm²)
A laboratory electrochemical and photovoltaic unit of current density equal to exactly 10 A/m².
History: Universal standard in solar cell photovoltaic characterization (short-circuit current density Jsc).
Common Uses: Silicon and perovskite solar cell short-circuit current density Jsc (typical silicon cells: 35–42 mA/cm²), lithium-ion battery charging rates.
❓ Frequently Asked Questions
How many Milliamperes per Square Centimeter are in 1 Ampere per Square Meter?
There are exactly 0.1 Milliamperes per Square Centimeter in 1 Ampere per Square Meter (1 A/m² = 0.1 mA/cm²).
What is the formula to convert Ampere per Square Meter to Milliampere per Square Centimeter?
