1 megajoule equals 1000 kilojoules. This conversion is straightforward because 1 megajoule (MJ) is equal to 1,000,000 joules, and 1 kilojoule (kJ) is 1,000 joules, making the conversion a simple multiplication by 1,000.
To explain, since 1 megajoule is 1,000,000 joules and 1 kilojoule is 1,000 joules, dividing the number of joules in a megajoule by 1,000 gives the amount in kilojoules. So, converting involves multiplying the megajoule value by 1000, because each megajoule contains 1,000 kilojoules.

Conversion Formula
The conversion from megajoule to kilojoule uses the formula: kilojoules = megajoules × 1000. This works because 1 megajoule equals 1,000 kilojoules, and multiplying the number of megajoules by 1000 gives the amount in kilojoules. For example, converting 2 megajoules: 2 × 1000 = 2000 kilojoules.
Conversion Example
- Convert 3 megajoules:
- Step 1: Write down the value in megajoules: 3 MJ.
- Step 2: Multiply by 1000: 3 × 1000 = 3000.
- Step 3: Result is 3000 kilojoules.
- Convert 0.5 megajoules:
- Step 1: Write down the value: 0.5 MJ.
- Step 2: Multiply by 1000: 0.5 × 1000 = 500.
- Step 3: Result in kilojoules is 500.
- Convert 10 megajoules:
- Step 1: Write down 10 MJ.
- Step 2: Multiply 10 by 1000: 10 × 1000 = 10,000.
- Step 3: The answer is 10,000 kilojoules.
