About these units
Megajoule
The megajoule became the preferred SI energy unit for large values after the international adoption of SI in the mid-20th century. Calorific values of fuels and food energy density are often expressed in MJ/kg in scientific publications.
Kilowatt-hour
The kilowatt-hour is the practical billing unit for electricity. Its familiarity makes it useful when communicating energy values to consumers, despite not being an SI unit.
