Converting amp hours (Ah) to watt hours (Wh) is a simple calculation. Multiply the amp hours by the voltage to obtain the watt hours. The formula is: Wh = Ah * V. For example, if you have a 100 Ah battery with a voltage of 12V, the calculation would be 100 Ah * 12V = 1200 Wh.

Ah to Wh Basic Formula
You can use a similar formula to get Amp Hours.
Formula: Amp hours(Ah) = Watt hours (Wh) / Voltage (V)
For example: For example, if you know that your battery energy value is 3000Wh and the voltage is 12 volts, using the formula Ah= Wh/ V, you can convert this to amperage hours :3000Wh/12V=250Ah.
