How to Convert Amp-Hours (Ah) to Watt-Hours (Wh)

Converting amp-hours to watt-hours is a common task when dealing with battery capacity and energy consumption. This process involves understanding the relationship between electrical charge, voltage, and energy.

Conversion Formula

The formula to convert amp-hours to watt-hours is:

\[Wh = Ah \times V\]

Where:

  • Wh is the energy in watt-hours
  • Ah is the capacity in amp-hours
  • V is the voltage in volts

Calculation Steps

  1. Identify the battery capacity in amp-hours (Ah)
  2. Determine the voltage of the battery or system
  3. Multiply the amp-hours by the voltage to get watt-hours (Wh)
  4. Round the result to an appropriate number of decimal places

Example Calculation

Let's convert 100 Ah at 12 V to watt-hours:

  1. Battery capacity: 100 Ah
  2. Voltage: 12 V
  3. Calculate watt-hours: \[100 \text{ Ah} \times 12 \text{ V} = 1200 \text{ Wh}\]

Therefore, 100 Ah at 12 V is equal to 1200 Wh.
