Calculating Amp Hours from Watt Hours
Calculating Amp Hours from Watt Hours
Now that we understand the basics of amp hours and watt hours, let’s delve into how to calculate amp hours from watt hours. This calculation can be useful in determining the capacity of a battery and estimating its runtime.
To convert watt hours to amp hours, you need to know the voltage of the battery. The formula is simple: divide the watt hour rating by the voltage. For example, if you have a 500-watt hour battery with a voltage of 12 volts:
Amp Hours = Watt Hours / Voltage
Amp Hours = 500 Wh / 12 V
Amp Hours ≈ 41.67 Ah
So, in this case, our 500-watt hour battery has an approximate capacity of 41.67 amp hours.
It’s important to note that this calculation provides an estimate and may not account for factors like inefficiencies or variations in real-world usage conditions. Nonetheless, it serves as a useful starting point when determining which battery size is suitable for your specific application.
By understanding how to calculate amp hours from wattage, you can make more informed decisions when selecting batteries for various devices and applications.
