megajoules
Million-joule measurements
Megajoules is the plural of megajoule, a unit of energy equal to one million joules.
The megajoule appears in scientific and engineering contexts where ordinary joules would produce unwieldy numbers: The explosion released about 4.2 megajoules of energy.
One kilowatt-hour equals 3.6 megajoules.
