Converting from Kilojoule (kJ) to Megacalorie (Mcal) | Energy

What is Kilojoule (kJ)

Kilojoule (kJ) is a unit of energy commonly used in the International System of Units (SI). It is equivalent to 1000 joules and is often used to quantify food energy content and energy expenditure.

What is Megacalorie (Mcal)

Megacalorie (Mcal) is a unit of energy equal to one million calories. It is commonly used in nutrition to measure the energy content of foods. One megacalorie is equivalent to 4186.8 kilojoules.

Conversion Formulas

The conversion between kilojoules (kJ) and megacalories (Mcal) can be done using the following formulas:

• To convert from kilojoules to megacalories: Mcal=kJ×0.0002388459
• To convert from megacalories to kilojoules: kJ=Mcal×4186.8
