Amp Hours to Watt Hours Formula

To convert ah to wh, you can use the following formula

Wh = Ah x v

  • Wh = kilowatt-hour
  • Ah = Ampere-hour
  • V = Voltage in volts

How to Calculate Amp Hours to Watt Hours?

To calculate amp-hours to watt-hours, you need to multiply the amp-hours by the voltage of the battery.

For example, if you have a battery with a voltage of 12 volts and 3 amp hours, the watt hours would be 12 x 3, or 36 watt hours.
