Convert Milliamperes per square metre to Gigaamperes per square metre
Convert Milliamperes per square metre (mA/m²) to Gigaamperes per square metre (GA/m²) instantly and accurately.
Conversion Formula
GA/m² = mA/m² × 1.000000000e-12
About Milliamperes per square metre
The milliampere per square metre (mA/m²) equals 10⁻³ A/m². Cathodic protection current density applied to reinforced concrete structures is 2-20 mA/m²; faradaic current density during slow anodic dissolution of iron in dilute H2SO4 is 1-100 mA/m²; exchange current density of the oxygen reduction reaction on platinum is ≈2 mA/m². 1 mA/m² = 10⁻³ A/m² = 0.1 µA/cm².
About Gigaamperes per square metre
The gigaampere per square metre (GA/m²) equals 10⁹ A/m², the extreme scale for thermonuclear plasmas and ultra-fast pulsed discharges. Current density in the compressed plasma of a z-pinch at peak compression is 1-100 GA/m²; field-emission current density from a sharp metallic tip at the Fowler-Nordheim threshold is ≈1-10 GA/m². 1 GA/m² = 10⁹ A/m² = 10³ MA/m².
