Coulomb to ampere hour Conversion
1 coulomb (C) is equal to 0.0002777777778 ampere hour (A·h).
1 C = 0.0002777777778 A·h
or
1 A·h = 3600 C
Formula
To convert a electric charge from coulomb (C) to ampere hour (A·h), divide the electric charge in coulomb by 3600
e(A·h) = e(C) / 3600
Examples:
Convert 250 coulomb to ampere hour:
e(A·h) = 250C / 3600 = 0.06944444444 A·h
