Convert Milliamperes per weber to Gigaamperes per weber
Convert Milliamperes per weber (mA/Wb) to Gigaamperes per weber (GA/Wb) instantly and accurately.
Conversion Formula
GA/Wb = mA/Wb × 1.000000000e-12
About Milliamperes per weber
The milliampere per weber (mA/Wb) equals 10⁻³ H⁻¹. A 500-turn coil on a large annealed nickel-iron toroid with L = 250 H has ℛ = N²/L = 1 000 mA/Wb; power-frequency toroidal current transformers with very-high-permeability cores can approach this scale. 1 mA/Wb = 10⁻³ H⁻¹.
About Gigaamperes per weber
The gigaampere per weber (GA/Wb) equals 10⁹ H⁻¹. The scale for small air gaps and miniaturized cores: a 0.1 mm air gap with 1 mm² cross-section has ℛ = 0.1×10⁻³ / (1.257×10⁻⁶ × 10⁻⁶) ≈ 80 GA/Wb; MEMS micro-inductors and integrated on-chip magnetics operate in the GA/Wb range. 1 GA/Wb = 10⁹ H⁻¹.
