About Femtoamperes
The femtoampere (fA) equals 10⁻¹⁵ A, encountered in patch-clamp background noise, advanced CMOS sub-threshold leakage, and electrochemical scanning probe measurements. Individual ion channels in biological membranes produce baseline noise currents of a few femtoamperes; the off-state leakage of a modern 3 nm transistor is well below 1 fA per device. 1 fA = 10⁻³ pA = 10³ aA.
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.
