Conversion Formula

aC = kAh × 3.600000000e+24

About Kiloampere-hours

The kiloampere-hour (kAh) equals 3.6 × 10⁶ C = 3.6 MC, the practical unit for grid-scale battery storage and large industrial electrolysis. A 100 MW·h utility-scale lithium-ion installation delivers roughly 27 kAh at typical operating voltages; aluminium Hall-Heroult cells consume approximately 13 500 kAh per tonne of aluminium. 1 kAh = 10³ Ah = 3.6 MC.

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.
