Convert coulombs (C), milliampere-hours (mAh), and ampere-hours (Ah). Electric charge (Q) is measured in coulombs; 1 C = 1 A·s. Battery capacity is often quoted in mAh or Ah.
This electric charge converter transforms values from Coulombs (C) to Ampere Hours (Ah). Results update instantly using the exact conversion factor.
The coulomb (C) is the SI unit of electric charge (1 C = 1 A·s).
The Ampere Hours (Ah) is a unit of electric charge in the Charge category.
1 C ÷ 3600 = 0.000278 Ah
Ah = C ÷ 3600
To convert C to Ah, divide the value in C by 3600 (since 1 C = 0.000278 Ah). Equivalently, multiply by 0.000278. Example: 1 C = 1 C × 0.000278 = 0.000278 Ah.
10 C = 0.002778 Ah ÷ 3600 = 10 C
