Convert megajoule to kilowatt-second
Please provide values below to convert megajoule [MJ] to kilowatt-second [kW*s], or Convert kilowatt-second to megajoule.
1 MJ = 1000 kW*s. To convert megajoule to kilowatt-second, multiply the value by 1000; to go the other way, divide by it (1 kW*s = 0.001 MJ). Both units measure energy and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 MJ = 1000 kW*s
- 1 kW*s = 0.001 MJ
- 10 MJ = 10000 kW*s
- 100 MJ = 100000 kW*s
How to Convert Megajoule to Kilowatt-Second
1 MJ = 1000 kW*s
Example: convert 15 MJ to kW*s:
15 MJ = 15 × 1000 kW*s = 15000 kW*s

Megajoule
A megajoule (MJ) is a unit of energy equal to one million joules.
History/Origin
The megajoule was introduced as part of the metric system to measure large amounts of energy, especially in scientific and engineering contexts, aligning with the SI units established in the 20th century.
Current Use
The megajoule is used in fields such as physics, engineering, and energy industries to quantify large energy quantities, including in energy production, consumption, and scientific research.
Kilowatt-Second
A kilowatt-second (kW·s) is a unit of energy equal to the energy transferred or converted when a power of one kilowatt is applied for one second.
History/Origin
The kilowatt-second has been used historically in physics and engineering to quantify energy, especially in contexts where power and time are relevant, but it is less common than other energy units like joules or kilowatt-hours.
Current Use
Today, the kilowatt-second is primarily used in specialized fields such as electrical engineering and energy calculations, often for convenience in measuring short-term energy transfer, but it is largely replaced by the joule in most applications.
Frequently Asked Questions
