公式
## 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.
计算示例
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
常见问题
Why divide by 3,600?
One hour has 3,600 seconds, and one Coulomb equals one Ampere-second. So one Ampere-Hour equals 3,600 Coulombs. Dividing reverses this relationship.
What is the difference between Ah and mAh?
1 Ah = 1,000 mAh. Milliampere-hours (mAh) are used for smaller batteries like phone batteries. Ampere-hours (Ah) are used for larger batteries like car batteries.
How does Coulomb relate to electrons?
One Coulomb equals approximately 6.242 x 10^18 elementary charges (electrons). It is the SI base unit of electric charge.
