About Elementary charge
The elementary charge (e) is the magnitude of charge on a single proton or electron, defined exactly as 1.602 176 634 × 10⁻¹⁹ C in the 2019 SI revision. It is the quantum of electric charge - the smallest freely occurring charge in nature - and underpins all atomic and subatomic physics. A current of 1 A corresponds to 6.241 509 × 10¹⁸ elementary charges flowing per second.
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.
