- Amp Hour to Watt Hour (ah ↔ wh) Calculator
- Battery Capacity Calculator (Amp Hours)

## 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.

- First, determine the Wh (watt-hours).
- Next, determine the voltage (volts).
- Next, gather the formula from above = mAh = Wh*1000 / V.
- Finally, calculate the mAh from Wh.
- 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
