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 Milliampere Hours (mAh). Results update instantly using the exact conversion factor.
The coulomb (C) is the SI unit of electric charge (1 C = 1 A·s).
The milliampere-hour (mAh) measures battery capacity: 1 mAh = 3.6 C.
1 C ÷ 3.6 = 0.277778 mAh
mAh = C ÷ 3.6
To convert C to mAh, divide the value in C by 3.6 (since 1 C = 0.277778 mAh). Equivalently, multiply by 0.277778. Example: 1 C = 1 C × 0.277778 = 0.277778 mAh.
10 C = 2.777778 mAh ÷ 3.6 = 10 C
