Convert kilowatt-second to megajoule
Please provide values below to convert kilowatt-second [kW*s] to megajoule [MJ], or Convert megajoule to kilowatt-second.
1 kW*s = 0.001 MJ. To convert kilowatt-second to megajoule, multiply the value by 0.001; to go the other way, divide by it (1 MJ = 1000 kW*s). 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*s = 0.001 MJ
- 1 MJ = 1000 kW*s
- 10 kW*s = 0.01 MJ
- 100 kW*s = 0.1 MJ
How to Convert Kilowatt-Second to Megajoule
1 kW*s = 0.001 MJ
Example: convert 15 kW*s to MJ:
15 kW*s = 15 × 0.001 MJ = 0.015 MJ

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.
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.
Frequently Asked Questions
What is 1 kilowatt-second in megajoule?
1 kilowatt-second (kW*s) = 0.001 megajoule (MJ).
How do you convert kilowatt-second to megajoule?
Multiply the kilowatt-second value by 0.001. For example, 25 kW*s × 0.001 = 0.025 MJ.
What is 10 kilowatt-second in megajoule?
10 kW*s = 0.01 MJ.
Which unit is larger, the kilowatt-second or the megajoule?
The megajoule is the larger unit: 1 kW*s equals only 0.001 MJ.
