Convert Milliamperes to Femtoamperes
Convert Milliamperes (mA) to Femtoamperes (fA) instantly and accurately.
Conversion Formula
fA = mA × 1000000000000
About Milliamperes
The milliampere (mA) equals 10⁻³ A, the everyday unit in consumer electronics and safety standards. Standard LEDs operate at 5-30 mA; USB 2.0 ports supply up to 500 mA; USB-C fast-charging delivers 3 000-5 000 mA. The milliampere is also the clinically important range for electric shock - ventricular fibrillation threshold is around 100 mA, and 1 mA is the threshold of perception. 1 mA = 10⁻³ A = 10³ µA.
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.
