Convert kilowatt-hour to joule
Please provide values below to convert kilowatt-hour [kW*h] to joule [J], or Convert joule to kilowatt-hour.
1 kW*h = 3600000 J. To convert kilowatt-hour to joule, multiply the value by 3600000; to go the other way, divide by it (1 J = 2.77777777778e-07 kW*h). Both units measure energy and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 kW*h = 3600000 J
- 1 J = 2.77777777778e-07 kW*h
- 10 kW*h = 36000000 J
- 100 kW*h = 360000000 J
How to Convert Kilowatt-Hour to Joule
1 kW*h = 3600000 J
Example: convert 15 kW*h to J:
15 kW*h = 15 × 3600000 J = 54000000 J

Kilowatt-Hour
A kilowatt-hour (kW·h) is a unit of energy equal to the energy transferred or used when a power of one kilowatt is sustained for one hour.
History/Origin
The kilowatt-hour originated in the late 19th century with the development of electrical power systems, becoming a standard unit for measuring electrical energy consumption and billing.
Current Use
It is widely used today in electricity billing, energy consumption monitoring, and in various engineering and scientific applications to quantify electrical energy usage.
Joule
The joule (J) is the SI unit of energy, work, and heat, defined as the work done when a force of one newton acts over a distance of one meter.
History/Origin
The joule was named after James Prescott Joule in 1889 to honor his work in energy and thermodynamics. It was adopted as the SI unit of energy in 1948.
Current Use
The joule is widely used in physics, engineering, and everyday contexts to quantify energy, work, and heat in various applications, including electricity, mechanics, and thermodynamics.
