Convert Attoamperes to Microamperes
Convert Attoamperes (aA) to Microamperes (µA) instantly and accurately.
Conversion Formula
µA = aA × 1.000000000e-12
About Attoamperes
The attoampere (aA) equals 10⁻¹⁸ A, the scale of single-electron tunnelling currents in quantum devices. Individual electrons tunnelling through a molecular junction or quantum dot produce average currents of order 1-100 aA when measured at sub-microsecond resolution; cryogenic shot-noise electrometers achieve sub-attoampere sensitivity. 1 aA = 10⁻³ fA = 10⁻¹⁸ A.
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.
