Joules (J) to Kilojoules (kJ) Converter

The Conversion Formula

The formula for converting joules (J) to kilojoules (kJ) is:

\[kJ = \frac{J}{1000}\]

Where:

• kJ: Kilojoules
• J: Joules

Conversion Steps

1. Start with the number of joules you want to convert
2. Divide this number by 1000
3. The result is the equivalent number of kilojoules

Example Conversion

Let's convert 5000 joules to kilojoules:

\[kJ = \frac{5000 J}{1000} = 5 kJ\]

About Joules and Kilojoules

The joule (J) and kilojoule (kJ) are both units of energy in the International System of Units (SI).

• 1 joule is defined as the amount of energy transferred when a force of 1 newton acts over a distance of 1 meter.
• 1 kilojoule is equal to 1000 joules.

Kilojoules are often used when dealing with larger amounts of energy, such as in food energy content, while joules are more commonly used for smaller quantities of energy in scientific calculations.
