About Megajoule (MJ)

One million joules, the megajoule is used for expressing the energy content of fuels and industrial energy consumption. One liter of gasoline contains about 34 MJ of chemical energy, and industrial boiler outputs and building energy audits often use megajoules as the standard unit.

About Watt-hour (Wh)

One watt sustained for one hour equals 3,600 joules. The watt-hour is used for small-scale electrical energy measurements such as battery capacity in consumer electronics. A smartphone battery typically holds 10-20 Wh, and laptop batteries range from 40 to 100 Wh.
