Conversion Formula
kC = Ah × 3.6
About Ampere-hours
The ampere-hour (Ah) equals exactly 3 600 C and is the universal capacity unit for rechargeable batteries. Lead-acid car batteries are rated 40-100 Ah; EV traction packs use 50-300 Ah cells; industrial forklift batteries exceed 1 000 Ah. Multiplying Ah by nominal voltage gives watt-hours of stored energy. 1 Ah = 3 600 C = 1 000 mAh.
About Kilocoulombs
The kilocoulomb (kC) equals 10³ C ≈ 0.278 Ah, used in industrial electrochemistry, large capacitor bank energy calculations, and fault current analysis. Electroplating a 100 cm² nickel layer 25 µm thick requires roughly 2-4 kC; power-factor-correction capacitor banks in substations may store several kilocoulombs. 1 kC = 10⁻³ MC = 10³ C.
