How to convert kilojoules to kilowatt hours (kJ to kWh)

The formula for converting kilojoules to kilowatt hours is: kWh = kJ × 0.00027777777777778. To calculate the kilojoule value in kilowatt hours first substitute the kilojoule value into the preceding formula, and then perform the calculation. If we wanted to calculate 1 kilojoule in kilowatt hours we follow these steps:

kWh = kJ × 0.00027777777777778

kWh = 1 × 0.00027777777777778

kWh = 0.00027777777777778

In other words, 1 kilojoule is equal to 0.00027777777777778 kilowatt hours.

Example Conversion

Let's take a look at an example. The step-by-step process to convert 5 kilojoules to kilowatt hours is:

Understand the conversion formula: kWh = kJ × 0.00027777777777778
Substitute the required value. In this case we substitute 5 for kJ so the formula becomes: kWh = 5 × 0.00027777777777778
Calculate the result using the provided values. In our example the result is: 5 × 0.00027777777777778 = 0.0013888888888889 kWh

In summary, 5 kilojoules is equal to 0.0013888888888889 kilowatt hours.

Converting kilowatt hours to kilojoules

In order to convert the other way around i.e. kilowatt hours to kilojoules, you would use the following formula: kJ = kWh × 3600. To convert kilowatt hours to kilojoules first substitute the kilowatt hour value into the above formula, and then execute the calculation. If we wanted to calculate 1 kilowatt hour in kilojoules we follow these steps:

kJ = kWh × 3600

kJ = 1 × 3600

kJ = 3600

Or in other words, 1 kilowatt hour is equal to 3600 kilojoules.

Conversion Unit Definitions

What is a Kilojoule?

A kilojoule (kJ) is a metric unit of energy in the International System of Units (SI). One kilojoule is equal to 1,000 joules. It is commonly used in nutrition and chemistry to express the energy content of foods and the energy released or absorbed in chemical reactions.

In the context of nutrition, kilojoules are often used to measure the energy value of foods and beverages. The energy we obtain from the food we eat is usually expressed in kilojoules or kilocalories (commonly referred to as calories). One kilocalorie is approximately equal to 4.184 kilojoules.

In chemical reactions, especially in the field of thermodynamics, energy changes are frequently measured in joules or kilojoules. The prefix "kilo-" denotes a factor of 1,000, so 1 kilojoule is equivalent to 1,000 joules.

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.
