Ampere hour to coulomb Conversion
1 ampere hour (A·h) is equal to 3600 coulomb (C).
1 A·h = 3600 C
or
1 C = 0.0002777777778 A·h
Formula
To convert a electric charge from ampere hour (A·h) to coulomb (C), multiply the electric charge in ampere hour by 3600
e(C) = e(A·h) × 3600
Examples:
Convert 50 ampere hour to coulomb:
e(C) = 50A·h × 3600 = 180000 C
