Formula
The formula to convert given energy from Kilojoules to Watt-hour is:
Energy(Watt-hour) = Energy(Kilojoules)/3.6
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 Watt-hour.
Answer
Given:
Energy in Kilojoules = 7200 kJ
Converting Energy from Kilojoules to Watt-hour...
The formula to convert from Kilojoules to Watt-hour is:
Energy(Watt-hour) = Energy(Kilojoules)/3.6
Substitute given Energy(Kilojoules) = 7200 in the above formula.
Energy(Watt-hour) = 7200/3.6
Energy(Watt-hour) = 2000
Therefore, 7200 kJ is equal to 2000 Wh.
2
Consider that a water heater releases 10,000 kilojoules (kJ) of energy. Convert this energy release from kilojoules to Watt-hour.
Answer
Given:
Energy in Kilojoules = 10000 kJ
Converting Energy from Kilojoules to Watt-hour...
The formula to convert from Kilojoules to Watt-hour is:
Energy(Watt-hour) = Energy(Kilojoules)/3.6
Substitute given Energy(Kilojoules) = 10000 in the above formula.
Energy(Watt-hour) = 10000/3.6
Energy(Watt-hour) = 2777.7778
Therefore, 10000 kJ is equal to 2777.7778 Wh.

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.
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.
