Milliampere-hours to Ampere-hours Converter
Conversion:
1 Milliampere-hour (mAh) = 0.001 Ampere-hours (Ah)
1 Ampere-hour (Ah) = 1000 Milliampere-hours (mAh)
Conversion Formula:
Q(Ah) = Q(mAh) / 1000
Example:
Convert 3 milliampere-hours to ampere-hours:
Q(Ah) = 3mAh / 1000 = 0.003Ah
Conversion Result:
3 milliampere-hours is equal to 0.003 ampere-hours.
Overview
A Milliampere-hours to Ampere-hours Converter is an essential tool for converting between two common units of battery capacity measurement. This conversion is particularly important in:
Consumer electronics (smartphones, tablets, power banks)
Industrial battery systems
Electric vehicle specifications
Electrical engineering calculations
Key Concepts
1. Milliampere-hour (mAh)
Represents 1/1000th of an ampere-hour
Commonly used for smaller batteries
Example: A smartphone battery might be 4,000 mAh
2. Ampere-hour (Ah)
Standard unit for larger battery systems
Example: An electric car battery might be 60 Ah
Practical Conversion Examples
| mAh | Ah Calculation | Result |
|---|---|---|
| 500 mAh | 500 ÷ 1000 | 0.5 Ah |
| 2,500 mAh | 2,500 ÷ 1000 | 2.5 Ah |
| 10,000 mAh | 10,000 ÷ 1000 | 10 Ah |
| 45,000 mAh | 45,000 ÷ 1000 | 45 Ah |
Real-World Applications
1. Power Bank Capacity
A 20,000 mAh power bank = 20 Ah
Can charge a 3,000 mAh phone about 6-7 times
2. Electric Vehicles
- A 60 kWh EV battery with 400V system:
3. Solar Power Systems
A 200 Ah deep-cycle battery bank = 200,000 mAh
Implementation Methods
1. Manual Calculation
Simply move the decimal point three places:
3,000 mAh → 3.000 Ah
0.75 Ah → 750 mAh
