Milliamp-Hour to Watt-Hour Converter
How to Convert Milliamp-hours (mAh) to Watt-hours (Wh)
To convert Milliamp-hours (mAh) to Watt-hours (Wh), use the formula:
mAh to Wh Calculation Formula
The relationship between milliamp-hours and watt-hours can be expressed as:
Wh = (mAh × V) ÷ 1000Where:
- mAh = Milliamp-hours
- Wh = Watt-hours
- V = Voltage (in volts)
Example Calculation
If you have a battery rated at 2000 mAh and operates at a voltage of 5V, the calculation would be:
Wh = (2000 mAh × 5) ÷ 1000 = 10 WhWhat is a Milliamp-hour (mAh)?
A milliamp-hour (mAh) is a unit of electric charge that indicates how much current a battery can provide over a specific period. For example, a battery rated at 1000 mAh can theoretically provide 1000 milliamps for one hour.
What is a Watt-hour (Wh)?
A watt-hour (Wh) is a unit of energy that measures the amount of work done or energy consumed over time. It represents the energy used when one watt of power is consumed for one hour. For example, a 60-watt light bulb running for one hour uses 60 Wh of energy.
The Simple Math Behind the Conversion
To convert milliamp-hours to watt-hours, you need to know the voltage of the system. The formula takes into account the voltage to determine how many watt-hours are equivalent to the given milliamp-hours. Here’s a breakdown:
- 1000 mAh at 5V = 5 Wh
- 2000 mAh at 12V = 24 Wh
- 500 mAh at 3.7V = 1.85 Wh
milliamp-hour (mAh) to Watt-hour (Wh) Conversion Table
Formula: Wh = (mAh × V) / 1000
