What is a Joule?
The Joule (J) is the SI derived unit of energy. It is defined as the work done by a force of one newton displacing a mass by one meter.
What is a Kilojoule?
The Kilojoule (kJ) is a unit of energy equal to 1,000 joules. It is famously used on food labels to express energy value (alongside calories).
How to Convert Joule to Kilojoule
To convert Joule to Kilojoule, divide the Joule value by 1000.
kJ = J ÷ 1000Manual Calculation Steps
Step 1: Identify the Formula
The standard formula to convert from Joule to Kilojoule is:
kJ = J ÷ 1000Step 2: Plug in the Value
Substitute the value you want to convert (for example, 5 J) into the formula.
Step 3: Calculate the Result
Perform the calculation to get the result in Kilojoule.
