Converting watt hours (Wh) to amp hours (Ah) is a simple calculation. To convert Wh to Ah, divide the watt hours by the voltage (V). The formula is Ah = Wh / V. For example, if you have a 1000 Wh battery with a voltage of 12V, the calculation would be 1000 Wh / 12V = 83.33 Ah. Use our watt hours to amp hours conversion calculator for easy and accurate conversions at different voltage levels.

Wh to Ah Basic Formula
To convert watt hours to amp hours, you need to know the voltage of the system. The formula is:
Amp Hours (Ah)=Watt Hours (Wh)/Voltage (V)
For instance, if you have a 1200 Wh lithium battery operating at 12V, the calculation would be:
100 Ah=1200 Wh/12 V
Wh to Ah Step-by-Step Example
Imagine you’re working with a 300 Wh battery at 24V. To find the amp hours:
Amp Hours (Ah)=300 Wh/24 V≈12.5 Ah
