Convert Statamperes to Milliamperes
Convert Statamperes (statA) to Milliamperes (mA) instantly and accurately.
Conversion Formula
mA = statA × 3.335640952e-7
About Statamperes
The statampere (statA) is the current unit of the CGS-Gaussian system, equal to 1 statC/s = 1/(10c) A ≈ 3.336 × 10⁻¹⁰ A (exact, since c = 2.997 924 58 × 10⁸ m/s is exact). Two long parallel wires each carrying 1 statA and separated by 1 cm experience a force of 1/c² dyn per centimetre. The statampere is used in electrostatics texts where Coulomb's law is written without ε₀. 1 statA ≈ 333.6 pA.
About Milliamperes
The milliampere (mA) equals 10⁻³ A, the everyday unit in consumer electronics and safety standards. Standard LEDs operate at 5-30 mA; USB 2.0 ports supply up to 500 mA; USB-C fast-charging delivers 3 000-5 000 mA. The milliampere is also the clinically important range for electric shock - ventricular fibrillation threshold is around 100 mA, and 1 mA is the threshold of perception. 1 mA = 10⁻³ A = 10³ µA.
