Convert Kiloamperes to Femtoamperes
Convert Kiloamperes (kA) to Femtoamperes (fA) instantly and accurately.
Conversion Formula
fA = kA × 1.000000000e+18
About Kiloamperes
The kiloampere (kA) equals 10³ A, the scale of industrial arc furnaces, short-circuit fault currents in power networks, and lightning return strokes. Medium-frequency induction furnaces for steel melting operate at 1-10 kA; substation busbar faults can reach 50-100 kA; a typical cloud-to-ground lightning stroke carries 10-30 kA for tens of microseconds. 1 kA = 10³ A = 10⁻³ MA.
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.
