Enter the input Watt-hour value in the text field.
The calculator converts the given Watt-hour into Kilojoules in realtime ⌚ using the conversion formula, and displays under the Kilojoules label. You do not need to click any button. If the input changes, Kilojoules value is re-calculated, just like that.
You may copy the resulting Kilojoules 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 Watt-hour to Kilojoules?
The formula to convert given energy from Watt-hour to Kilojoules is:
Energy(Kilojoules) = Energy(Watt-hour) × 3.6
Substitute the given value of energy in watt-hour, i.e., Energy(Watt-hour) in the above formula and simplify the right-hand side value. The resulting value is the energy in kilojoules, i.e., Energy(Kilojoules).
Calculation
Calculation will be done after you enter a valid input.
Examples
1
Consider that we have a light bulb that consumes 300 watt-hours (Wh) of energy over the 5 hours it was on. Convert this energy consumption from watt-hours to Kilojoules.
Answer:
Given:
The energy in watt-hour is:
Energy(Watt-hour) = 300
Formula:
The formula to convert energy from watt-hour to kilojoules is:
Energy(Kilojoules) = Energy(Watt-hour) × 3.6
Substitution:
Substitute given weight Energy(Watt-hour) = 300 in the above formula.
Energy(Kilojoules) = 300 × 3.6
Energy(Kilojoules) = 1080
Final Answer:
Therefore, 300 Wh is equal to 1080 kJ.
The energy is 1080 kJ, in kilojoules.
2
Consider that a rechargeable battery stores 500 watt-hours (Wh) of energy. Convert this stored energy from watt-hours to Kilojoules.
Answer:
Given:
The energy in watt-hour is:
Energy(Watt-hour) = 500
Formula:
The formula to convert energy from watt-hour to kilojoules is:
Energy(Kilojoules) = Energy(Watt-hour) × 3.6
Substitution:
Substitute given weight Energy(Watt-hour) = 500 in the above formula.
Energy(Kilojoules) = 500 × 3.6
Energy(Kilojoules) = 1800
Final Answer:
Therefore, 500 Wh is equal to 1800 kJ.
The energy is 1800 kJ, in kilojoules.

Watt-hour
A Watt-hour (Wh) is a unit of energy that measures the amount of electrical energy consumed or generated over time. One Watt-hour is equivalent to one watt of power used or produced for one hour. This unit is commonly used to quantify energy usage in households, industries, and various devices. For instance, a 100-watt light bulb running for 10 hours consumes 1000 watt-hours, or 1 kilowatt-hour (kWh). Watt-hours are essential for understanding energy consumption, billing in electric utilities, and managing energy efficiency.
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.
Frequently Asked Questions (FAQs)
1. What is the formula for converting Watt-hour to Kilojoules in Energy?
