Conversion Formula

C = kC × 1000

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.

About Coulombs

The coulomb (C) is the SI derived unit of electric charge, equal to the charge transported by a current of 1 A in 1 s. In the 2019 SI revision it is fixed exactly via the elementary charge: 1 C = 1 / (1.602 176 634 × 10⁻¹⁹) e ≈ 6.241 × 10¹⁸ e. Practical benchmarks: a 1 Ah battery stores 3 600 C; a lightning bolt transfers 1-20 C.
