Enter the kilowatt-hours and the volts into the Calculator. The calculator will evaluate the Amps from kWH. 

Amps from kWH Formula

A = kWH / V * 1000


  • A is the Amps from kWH (amps)
  • kWH is the kilowatt-hours
  • V (volts) is the volts

To calculate Amps from kWH, divide the kilowatt-hours by the voltage, then multiply by 1000.

How to Calculate Amps from kWH?

The following steps outline how to calculate the Amps from kWH.

  1. First, determine the kilowatt-hours. 
  2. Next, determine the volts. 
  3. Next, gather the formula from above = A = kWH / V * 1000.
  4. Finally, calculate the Amps from kWH.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

kilowatt-hours = 123

volts = 10


What is a kilowatt-hour (kWh)?

A kilowatt-hour (kWh) is a measure of energy that represents the amount of energy produced or consumed in one hour by a device with a power of one kilowatt. It is commonly used to measure electricity consumption by utilities.

Why do we need to convert kWh to Amps?

Converting kWh to Amps is useful for understanding the current draw of an electrical system or device, especially when planning electrical installations or assessing electrical load. This conversion helps in ensuring that electrical systems are not overloaded and are designed efficiently.

Can I use the same formula to convert kWh to Amps for AC and DC circuits?

While the basic formula (A = kWh / V * 1000) can be used for both AC and DC circuits, it’s important to consider that AC circuits may require additional factors such as power factor and phase angle in more complex calculations. For basic conversions, this formula provides a good starting point.

How does voltage affect the conversion from kWh to Amps?

Voltage plays a crucial role in the conversion from kWh to Amps. Since the formula involves dividing the energy (in kWh) by the voltage (in volts), a higher voltage will result in a lower current (Amps) for the same amount of energy consumption. This is why devices operating at higher voltages are often more efficient in transmitting electrical power.
