About these units
The joule (J) is an SI base or derived unit of energy & work.
The megajoule (MJ) is a metric unit of energy & work, equal to 1,000,000 joules.
Going the other way, 1 megajoule = 1,000,000 joules. Diet calories, electricity bills in kilowatt-hours, boiler ratings in BTU and particle physics in electronvolts are all the same physical quantity. Convert energy across every scale from the atomic to the industrial.
