Convert Attocoulombs (aC) to Microampere-hours (µAh) instantly and accurately.
Conversion Formula
µAh = aC × 2.777777778e-16
About Attocoulombs
The attocoulomb (aC) equals 10⁻¹⁸ C, sitting between the elementary charge and the femtocoulomb. It arises in ultra-sensitive charge measurements: single-electron transistors, quantum capacitance probing of graphene and 2D materials, and scanning tunnelling microscopy where tip-sample charge exchange is tracked at this scale. 1 aC = 10⁻³ fC ≈ 6.24 e.
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.
