Concept introduction:

Energy is defined as the capacity to do work or transfer heat.

The S.I. unit of energy is joule $\left(\text{J}\right)$.

Calorie $\left(\text{cal}\right)$ is a unit of energy.

The relation between calories and joules is given below.

$1\text{cal}=4.184\text{J}$

The conversion of energy from joules into calories, the conversion factor is $\frac{1\text{cal}}{4.184\text{J}}$
