Wh to mAh Calculator

Formula

The formula to calculate mAh from Wh is:

\[ \text{mAh} = \frac{\text{Wh} \times 1000}{\text{V}} \]

Where:

\(\text{mAh}\) is the milliampere-hours
\(\text{Wh}\) is the watt-hours
\(\text{V}\) is the voltage

What is Wh to mAh?

The conversion from watt-hours (Wh) to milliampere-hours (mAh) is a common calculation in electronics and battery technology. It helps determine the capacity of a battery in terms of how long it can power a device. By knowing the watt-hours and the voltage, you can easily calculate the milliampere-hours, which is a more practical unit for specifying battery capacity.

Example Calculation

Let's assume the following values:

Watt-Hours (Wh) = 5 Wh
Voltage (V) = 3.7 V

Using the formula:

\[ \text{mAh} = \frac{5 \times 1000}{3.7} \approx 1351.35 \text{ mAh} \]

The mAh is approximately 1351.35 mAh.
