What does 1 megajoule represent?

1 megajoule (MJ) is an SI derived unit of energy equal to one million joules, measuring energy transfer or storage such as heat, work, or electrical energy.

Why convert megajoules to kilocalories (th)?

Conversion is useful to relate large-scale energy quantities to dietary energy content or heat quantities used in nutrition, thermal engineering, and some chemical contexts.

Are kilocalorie (th) and regular calories the same?

Kilocalorie (th) refers to thermochemical calories defined exactly as 4184 joules, which may differ slightly from other calorie definitions.
