  1. 1 Ah = 3600 C
  2. 1 × 3600 = 3600 C

How to convert ampere-hours to coulombs

1 Ah = 3,600 C, so multiply by 3,600 to go from ampere-hours to coulombs. Going the other way, 1 C = 0.000277777777778 Ah.

C = Ah × 3,600
Ah = C × 0.000277777777778

Worked example:

1 Ah = 3600 C
5 × 3600 = 18000 C
