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 Microampere-hours

The microampere-hour (µAh) equals exactly 3.6 mC (= 10⁻⁶ A × 3 600 s), a practical capacity unit for ultra-low-power wireless sensors and IoT devices. Bluetooth Low Energy (BLE) beacons typically consume 1-10 µAh per advertising event; coin-cell RTC circuits track self-discharge in µAh per month. 1 µAh = 10⁻³ mAh = 3.6 mC.
