Understanding the Difference between Volts and Kilowatt-hours (kWh)

When it comes to electrical energy, there are several units of measurement that are used to quantify and understand the flow of electricity. Two of the most common units are volts (V) and kilowatt-hours (kWh). While they are related, they are not interchangeable, and it's essential to understand the difference between them.

What are Volts (V)?

Volts are the units of electrical potential difference or electromotive force. In simple terms, volts measure the "pressure" that drives electric current through a circuit. The higher the voltage, the greater the force pushing the electric current. Volts are usually represented by the symbol "V".

For example, a typical household outlet in the United States provides 120 volts of electricity. This means that there is a potential difference of 120 volts between the positive and negative terminals of the outlet.

What are Kilowatt-hours (kWh)?

Kilowatt-hours, on the other hand, are units of energy. They measure the total amount of electrical energy consumed or produced over a period of time. Kilowatt-hours are usually represented by the symbol "kWh".

One kilowatt-hour is equivalent to one thousand watt-hours. To put it into perspective, if you use a 100-watt light bulb for 10 hours, you would have consumed 1 kilowatt-hour (kWh) of electricity.

Key Differences between Volts and Kilowatt-hours

Here are the key differences between volts and kilowatt-hours:

Voltage vs. Energy

  • Volts measure the voltage or potential difference between two points.
  • Kilowatt-hours measure the total energy consumed or produced.


  • Volts are measured in volts (V).
  • Kilowatt-hours are measured in kilowatt-hours (kWh).


  • Volts are used to describe the electrical potential of a circuit or device.
  • Kilowatt-hours are used to measure the energy consumption or production of a device or system over time.

Real-World Examples

To illustrate the difference, consider the following scenarios:

  • A 12-volt car battery provides 12 volts of electricity, but it can supply energy for several hours depending on its capacity. The energy consumed from the battery would be measured in kilowatt-hours (kWh).
  • A household electricity bill typically shows the total energy consumption in kilowatt-hours (kWh) over a billing period. This is a measure of the total energy consumed, not the voltage.


In conclusion, volts and kilowatt-hours are two distinct units of measurement that serve different purposes in the context of electrical energy. Volts measure the electrical potential or voltage, while kilowatt-hours measure the total energy consumed or produced over time. Understanding the difference between these units is essential for accurate calculations and efficient use of electrical energy.
