Conversion formula

Coulomb to Milliampere-hour formula: value in mAh = value in C × 0.27777777777778.

Milliampere-hour to Coulomb formula: value in C = value in mAh × 3.6.

How to convert Coulomb to Milliampere-hour

To convert Coulomb to Milliampere-hour, multiply the value in C by 0.27777777777778. This gives the result in mAh.

For example, 1 C = 0.27777777777778 mAh and 10 C = 2.7777777777778 mAh.

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.

What is Milliampere-hour?

Milliampere-hour (mAh): Smaller battery-charge capacity scale, common on portable devices. Battery energy also depends on voltage; an Ah or mAh value alone does not give watt-hours. 1 mAh = 0.001 Ah = 3.6 C.
