Conversion formula

Ampere-hour to Coulomb formula: value in C = value in Ah × 3600.

Coulomb to Ampere-hour formula: value in Ah = value in C × 0.00027777777777778.

How to convert Ampere-hour to Coulomb

To convert Ampere-hour to Coulomb, multiply the value in Ah by 3600. This gives the result in C.

For example, 1 Ah = 3600 C and 10 Ah = 36000 C.

What is Ampere-hour?

Ampere-hour (Ah): Battery charge capacity; the load current determines how long it can supply charge. Battery energy also depends on voltage; an Ah or mAh value alone does not give watt-hours. 1 Ah = 1 A × 1 h = 3600 C.

What is Coulomb?

Coulomb (C): SI charge, equivalent to one ampere flowing for one second. Battery energy also depends on voltage; an Ah or mAh value alone does not give watt-hours. 1 C = 1 A·s; 3600 C = 1 Ah.
