Convert Picoamperes to Milliamperes
Convert Picoamperes (pA) to Milliamperes (mA) instantly and accurately.
Conversion Formula
mA = pA × 1.000000000e-9
About Picoamperes
The picoampere (pA) equals 10⁻¹² A, the standard scale for electrometer measurements, reverse-bias diode leakage, and single ion-channel currents in patch-clamp electrophysiology. A typical open potassium channel carries 1-20 pA; high-quality electrometer inputs resolve below 1 pA; insulation resistance measurements on cables are reported in pA at known voltage. 1 pA = 10⁻³ nA = 10³ fA.
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.
