A megajoule (MJ) is an SI derived unit of energy equal to one million joules used to measure transferred or stored energy.

What does kilocalorie (IT) represent?

Kilocalorie (IT) equals 1,000 international-table calories, with one international-table calorie defined as 4.1868 joules.

Why convert megajoules to kilocalories (IT)?

To translate large-scale SI energy values into traditional units used in thermodynamics and older engineering literature.
