Unit definitions

Kilojoule

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

Joule

The joule is the SI unit of energy. It is defined as the work done when a force of one newton is applied over a distance of one meter.

How to convert Kilojoule to Joule

$$\text{Energy}_{\text{J}} = \text{Energy}_{\text{kJ}} \cdot {10}^{3}$$

Examples

Example 1

Convert $45.0\ \text{kJ}$ to $\text{J}$.

$$\text{Energy}_{\text{J}} = 45.0 \cdot {10}^{3}$$

$$\text{Energy}_{\text{J}} = 45000$$

$$\therefore \ 45.0\ \text{kJ} = 45000 \ \text{J}$$

Example 2

Convert $60.0\ \text{kJ}$ to $\text{J}$.

$$\text{Energy}_{\text{J}} = 60.0 \cdot {10}^{3}$$

$$\text{Energy}_{\text{J}} = 60000$$

$$\therefore \ 60.0\ \text{kJ} = 60000 \ \text{J}$$

Example 3

Convert $110.0\ \text{kJ}$ to $\text{J}$.

$$\text{Energy}_{\text{J}} = 110.0 \cdot {10}^{3}$$

$$\text{Energy}_{\text{J}} = 110000$$

$$\therefore \ 110.0\ \text{kJ} = 110000 \ \text{J}$$

Example 4

Convert $140.0\ \text{kJ}$ to $\text{J}$.

$$\text{Energy}_{\text{J}} = 140.0 \cdot {10}^{3}$$

$$\text{Energy}_{\text{J}} = 140000$$

$$\therefore \ 140.0\ \text{kJ} = 140000 \ \text{J}$$

Example 5

Convert $170.0\ \text{kJ}$ to $\text{J}$.

$$\text{Energy}_{\text{J}} = 170.0 \cdot {10}^{3}$$

$$\text{Energy}_{\text{J}} = 170000$$

$$\therefore \ 170.0\ \text{kJ} = 170000 \ \text{J}$$
