Conversion Formula
aF = µF × 1000000000000
About Microfarads
The microfarad (µF) equals 10⁻⁶ F, the practical scale for power supply filtering, motor-run capacitors, and audio crossovers. Aluminium electrolytic capacitors range from 1 µF to 100 000 µF; DC link bus capacitors in inverter drives are 100-1 000 µF; motor-run capacitors are 1-100 µF per phase; audio crossover networks use 1-100 µF film capacitors. 1 µF = 10⁻³ mF = 10⁻⁶ F.
About Attofarads
The attofarad (aF) equals 10⁻¹⁸ F, the scale for quantum-mechanical and nanoscale capacitances. Carbon-nanotube transistor gate capacitances are 1-100 aF; single-electron tunnel junctions in Coulomb-blockade devices operate in the attofarad range; scanning-probe microscopy tip-sample junctions at sub-nanometre separation approach 1 aF. 1 aF = 10⁻³ fF = 10⁻¹⁸ F.
