About These Units
Ampere-hour (Ah)
An ampere-hour (Ah) equals 3,600 coulombs—the charge delivered by 1 ampere flowing for 1 hour. Standard battery capacity unit: car batteries 50-100 Ah, deep-cycle batteries 100-400 Ah, EV batteries measured in kWh (Ah × voltage). One Ah = 1000 mAh.
Femtocoulomb (fC)
A femtocoulomb (fC) equals 10⁻¹⁵ coulombs or about 6,242 electrons. Used in single-electron transistors, quantum dot devices, and advanced semiconductor characterization. One electron has a charge of 0.16 fC (160 aC).
