Convert megajoule to joule
Enter a value below to convert megajoule [MJ] to joule [J]. Reverse conversion: Convert joule to megajoule.
1 MJ = 1000000 J. To convert megajoule to joule, multiply the value by 1000000; to go the other way, divide by it (1 J = 1e-06 MJ). Both units measure energy and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Megajoule: Definition and Use
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.
Joule: Definition and Use
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.
