The calculator converts the given Kilojoules into Joules in realtime ⌚ using the conversion formula, and displays under the Joules label. You do not need to click any button. If the input changes, Joules value is re-calculated, just like that.
You may copy the resulting Joules value using the Copy button.
To view a detailed step by step calculation of the conversion, click on the View Calculation button.
You can also reset the input by clicking on Reset button present below the input field.
What is the Formula to convert Kilojoules to Joules?
The formula to convert given energy from Kilojoules to Joules is:
Energy(Joules) = Energy(Kilojoules) × 1e3
Substitute the given value of energy in kilojoules, i.e., Energy(Kilojoules) in the above formula and simplify the right-hand side value. The resulting value is the energy in joules, i.e., Energy(Joules).
Calculation
Calculation will be done after you enter a valid input.
Examples
1
Consider that an electric motor releases 7,200 kilojoules (kJ) of energy. Convert this energy generation from Kilojoules to Joules.
Answer:
Given:
The energy in kilojoules is:
Energy(Kilojoules) = 7200
Formula:
The formula to convert energy from kilojoules to joules is:
Energy(Joules) = Energy(Kilojoules) × 1e3
Substitution:
Substitute given weight Energy(Kilojoules) = 7200 in the above formula.
Energy(Joules) = 7200 × 1e3
Energy(Joules) = 7200000
Final Answer:
Therefore, 7200 kJ is equal to 7200000 J.
The energy is 7200000 J, in joules.
2
Consider that a water heater releases 10,000 kilojoules (kJ) of energy. Convert this energy release from kilojoules to Joules.
Answer:
Given:
The energy in kilojoules is:
Energy(Kilojoules) = 10000
Formula:
The formula to convert energy from kilojoules to joules is:
Energy(Joules) = Energy(Kilojoules) × 1e3
Substitution:
Substitute given weight Energy(Kilojoules) = 10000 in the above formula.
Energy(Joules) = 10000 × 1e3
Energy(Joules) = 10000000
Final Answer:
Therefore, 10000 kJ is equal to 10000000 J.
The energy is 10000000 J, in joules.

Kilojoules
A Kilojoule (kJ) is a unit of energy equal to 1,000 joules. It is commonly used to measure energy in various scientific and engineering contexts, as well as in nutrition to quantify the energy content of foods. One kilojoule is the amount of energy required to apply a force of one newton over a distance of one kilometer, or the energy transferred when one kilowatt of power is applied for one second. Kilojoules are used in fields such as physics, chemistry, and engineering to quantify work, heat, and energy, providing a standard measure for comparing energy content and transfer across different systems and processes.
Joules
The Joule (J) is the SI unit of energy. One joule is defined as the amount of energy transferred when a force of one newton is applied over a distance of one meter. It can also be defined as the energy transferred when one watt of power is applied for one second. The joule is a versatile unit used in various scientific and engineering contexts to measure energy, work, and heat. It is commonly used in physics, chemistry, and engineering to quantify the energy content of fuels, the work done by machines, and the energy used or produced in electrical circuits.
Frequently Asked Questions (FAQs)
1. What is the formula for converting Kilojoules to Joules in Energy?
