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 Joules.
Answer
Given:
Energy in Watt-hour = 300 Wh
Converting Energy from Watt-hour to Joules...
The formula to convert from Watt-hour to Joules is:
Energy(Joules) = Energy(Watt-hour) × 3.6e3
Substitute given Energy(Watt-hour) = 300 in the above formula.
Energy(Joules) = 300 × 3.6e3
Energy(Joules) = 1080000
Therefore, 300 Wh is equal to 1080000 J.
2
Consider that a rechargeable battery stores 500 watt-hours (Wh) of energy.
Convert this stored energy from watt-hours to Joules.
Answer
Given:
Energy in Watt-hour = 500 Wh
Converting Energy from Watt-hour to Joules...
The formula to convert from Watt-hour to Joules is:
Energy(Joules) = Energy(Watt-hour) × 3.6e3
Substitute given Energy(Watt-hour) = 500 in the above formula.
Energy(Joules) = 500 × 3.6e3
Energy(Joules) = 1800000
Therefore, 500 Wh is equal to 1800000 J.

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.
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.
