How to Convert Coulombs to Ampere-Hours?

1 C = 2,7778⋅10-4 Ah

or

1 Ah = 3600 C

Coulombs to Ampere-Hours Formula

The quantity of electric charge, measured in ampere-hours (Ah), can be determined by dividing the charge in coulombs (C) by 3600:

Q(Ah) = Q(C) / 3600

Example

Let’s say we have a battery with a charge of 432,000 Coulombs. To convert this value into Ampere-hours (Ah), we can use the formula:

Ampere-hours (Ah) = Coulombs (C) / 3,600

Thus, for our example:

Ah = 432,000 C / 3,600 = 120 Ah

So, the battery has a charge of 120 Ampere-hours. This conversion is frequently used in practical applications, such as estimating the capacity of batteries used in electric vehicles or backup power systems.
