About Milliampere-hours
The milliampere-hour (mAh) equals exactly 3.6 C and is the universal capacity unit for portable-electronics batteries. Smartphone batteries range from 3 000-5 000 mAh; AA alkaline cells deliver ≈2 500 mAh; small lithium coin cells for RTC modules are rated 35-225 mAh. 1 mAh = 3.6 C = 10⁻³ Ah.
About Femtocoulombs
The femtocoulomb (fC) equals 10⁻¹⁵ C, used in radiation detection, MEMS sensors, and microelectronics charge characterisation. A single ionising particle traversing a thin silicon strip detector typically deposits 1-80 fC; noise floors of charge-sensitive amplifiers in nuclear instrumentation are specified in femtocoulombs. 1 fC = 10⁻³ pC = 10³ aC.
