About Millicoulombs
The millicoulomb (mC) equals 10⁻³ C, encountered in electroplating thin films, faradaic charge integration in voltammetry, and capacitor discharge testing. Cyclic voltammetry integration of an electrode adsorption peak typically yields 1-100 mC; a 1 mF supercapacitor at 1 V stores exactly 1 mC. 1 mC = 10⁻³ C = 10³ µC.
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.
