How to convert joules to kilowatt hours (J to kWh)

The formula for converting joules to kilowatt hours is: kWh = J × 0.00000027777777777778. To calculate the joule value in kilowatt hours first substitute the joule value into the preceding formula, and then perform the calculation. If we wanted to calculate 1 joule in kilowatt hours we follow these steps:

kWh = J × 0.00000027777777777778

kWh = 1 × 0.00000027777777777778

kWh = 0.00000027777777777778

In other words, 1 joule is equal to 0.00000027777777777778 kilowatt hours.


Example Conversion

Let's take a look at an example. The step-by-step process to convert 2 joules to kilowatt hours is:

  1. Understand the conversion formula: kWh = J × 0.00000027777777777778
  2. Substitute the required value. In this case we substitute 2 for J so the formula becomes: kWh = 2 × 0.00000027777777777778
  3. Calculate the result using the provided values. In our example the result is: 2 × 0.00000027777777777778 = 0.00000055555555555556 kWh

In summary, 2 joules is equal to 0.00000055555555555556 kilowatt hours.


Converting kilowatt hours to joules

In order to convert the other way around i.e. kilowatt hours to joules, you would use the following formula: J = kWh × 3600000. To convert kilowatt hours to joules first substitute the kilowatt hour value into the above formula, and then execute the calculation. If we wanted to calculate 1 kilowatt hour in joules we follow these steps:

J = kWh × 3600000

J = 1 × 3600000

J = 3600000

Or in other words, 1 kilowatt hour is equal to 3600000 joules.


Conversion Unit Definitions

What is a Joule?

A joule (J) is the standard unit of energy in the International System of Units (SI). It is defined as the amount of work done when a force of one newton is applied over a distance of one meter in the direction of the force. In other words, one joule is equal to the energy transferred when one watt of power is dissipated for one second.
Mathematically, 1 joule is equal to 1 N × 1 m, or 1 kg × m2/s2 in terms of mass, length, and time.
Joules are a versatile unit of measurement used not only in physics but also in various fields including engineering, chemistry, and biology to quantify energy, work, and heat. For example, it's commonly used to express the energy content of foods, the capacity of batteries, and the energy output of electronic devices.

What is a Kilowatt Hour?

A kilowatt-hour (kWh) is a unit of energy commonly used for measuring electricity consumption. It represents one kilowatt (kW) of power used continuously for one hour. In other words, it is a measure of energy equivalent to 1,000 watt-hours or 3.6 million joules.
Mathematically, 1 kilowatt-hour is equal to: 1 kWh = 1 kilowatt × 1 hour = 1,000 watts × 1 hour.
Kilowatt-hours are the standard billing units used by electric utilities for measuring the amount of energy consumed by residential, commercial, and industrial customers over time. For example, if you use a 1,000-watt (or 1 kilowatt) appliance for one hour, you will have consumed 1 kilowatt-hour of electricity. Utility bills often display the total energy consumption in kilowatt-hours, and consumers are charged based on the number of kilowatt-hours they use.
