What is Energy?
Energy is the capacity of a physical system to do work or produce heat. The SI unit is the joule (J), defined as the work done when a force of one newton is applied over one meter (1 J = 1 N·m = 1 kg·m²/s²). Other important units include the kilowatt-hour (kWh)—used on electricity bills (1 kWh = 3.6 MJ)—the calorie (cal)—used in nutrition (1 food Calorie = 1 kcal = 4,184 J)—and the electronvolt (eV), used in atomic and particle physics (1 eV = 1.602 × 10⁻¹⁹ J).
What is Calorie?
The calorie (symbol: cal) is a unit of energy traditionally used to measure heat and energy transfer. Although the joule (J) is the official SI unit of energy, the......(Read more on Calorie).
What is Kilojoule?
The kilojoule (kJ) is an SI-derived unit of energy equal to 1,000 joules (J). It is widely used to measure mechanical work, heat, electrical energy, chemical energy, and food energy. The kilojouleis commonly used in science, engineering, and nutrition because it expresses larger energy values more conveniently than the joule.

Calorie to Kilojoule Examples
Example 1:
Convert 0.2 Calorie energy to Kilojoule unit.
Solution:
We know that one Calorie is equivalent to 0.004184 Kilojoule.
Therefore,
0.2 cal = 0.2 x 0.004184 Kilojoule.
0.2 cal = 0.00083680000000000106 Kilojoule.
Hence, 0.2 Calorie is approximately equal to 0.00083680000000000106 Kilojoule.
Example 2:
Convert 10 Calorie energy to Kilojoule unit.
