How to Convert Coulombs to Ampere-Hours
Formula
Ah = Coulombs / 3,600
One Ampere-Hour is the charge transferred by a steady current of 1 Ampere flowing for 1 hour. Since 1 hour = 3,600 seconds and 1 Coulomb = 1 Ampere-second, dividing Coulombs by 3,600 yields Ampere-Hours.
Why This Matters
Battery capacity is commonly rated in Ah or mAh. Understanding the conversion helps when comparing battery specifications or calculating charge and discharge times.
Example Calculation
Convert 3,600 Coulombs to Ampere-Hours.
- 01One Ampere-Hour equals 3,600 Coulombs (1 A flowing for 3,600 seconds)
- 02Ah = 3,600 / 3,600 = 1 Ah
- 03mAh = 3,600 / 3.6 = 1,000 mAh
