Kilojoule

$10^{3} \ \text{J}$ is a kilojoule.

Calorie (small calorie)

The small calorie is the thermal energy required to raise the temperature of one gram of water by one degree Celsius. It is equal to $4.184 \ \text{J}$.

How to convert Kilojoule to Calorie (small calorie)

$$\text{Energy}_{\text{cal}} = \text{Energy}_{\text{kJ}} \cdot 239.0057361376673040152963671128107$$

Examples

Example 1

Convert $20.0\ \text{kJ}$ to $\text{cal}$.

$$\text{Energy}_{\text{cal}} = 20.0 \cdot 239.0057361376673040152963671128107$$

$$\text{Energy}_{\text{cal}} = 4780.114723$$

$$\therefore \ 20.0\ \text{kJ} = 4780.114723 \ \text{cal}$$

Example 2

Convert $90.0\ \text{kJ}$ to $\text{cal}$.

$$\text{Energy}_{\text{cal}} = 90.0 \cdot 239.0057361376673040152963671128107$$

$$\text{Energy}_{\text{cal}} = 21510.516252$$

$$\therefore \ 90.0\ \text{kJ} = 21510.516252 \ \text{cal}$$

Example 3

Convert $115.0\ \text{kJ}$ to $\text{cal}$.

$$\text{Energy}_{\text{cal}} = 115.0 \cdot 239.0057361376673040152963671128107$$

$$\text{Energy}_{\text{cal}} = 27485.659656$$

$$\therefore \ 115.0\ \text{kJ} = 27485.659656 \ \text{cal}$$

Example 4

Convert $135.0\ \text{kJ}$ to $\text{cal}$.

$$\text{Energy}_{\text{cal}} = 135.0 \cdot 239.0057361376673040152963671128107$$

$$\text{Energy}_{\text{cal}} = 32265.774379$$

$$\therefore \ 135.0\ \text{kJ} = 32265.774379 \ \text{cal}$$

Example 5

Convert $160.0\ \text{kJ}$ to $\text{cal}$.

$$\text{Energy}_{\text{cal}} = 160.0 \cdot 239.0057361376673040152963671128107$$

$$\text{Energy}_{\text{cal}} = 38240.917782$$

$$\therefore \ 160.0\ \text{kJ} = 38240.917782 \ \text{cal}$$
