Enter the Wh (watt-hours) and the voltage (volts) into the Calculator. The calculator will evaluate the mAh from Wh.

## mAh from Wh Formula

mAh = Wh*1000 / V

Variables:

• mAH is the mAh from Wh (maH (milli-amp hours))
• Wh is the Wh (watt-hours)
• V is the voltage (volts)

To calculate mAh from Wh, multiply the watt-hours by 1000, then divide by the voltage.

## How to Calculate mAh from Wh?

The following steps outline how to calculate the mAh from Wh.

1. First, determine the Wh (watt-hours).
2. Next, determine the voltage (volts).
3. Next, gather the formula from above = mAh = Wh*1000 / V.
4. Finally, calculate the mAh from Wh.
5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem :

Use the following variables as an example problem to test your knowledge.

Wh (watt-hours) = 675

voltage (volts) = 40
