Conversion Formula
pA = µA × 1000000
About Microamperes
The microampere (µA) equals 10⁻⁶ A, common in low-power sensor circuits, analogue signal conditioning, and bioelectrical measurement. Surface ECG electrodes record body currents of 1-100 µA; a 1 mW signal at 5 V draws 200 µA; modern low-power microcontrollers sleep at 1-10 µA, enabling coin-cell operation for months or years. 1 µA = 10⁻³ mA = 10³ nA.
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.
