How to Convert Kilojoules to Megajoules
To convert kilojoules to megajoules, divide the value by 1000.
The Formula
Megajoules = Kilojoules ÷ 1000
Key Fact
1 megajoule = 1000 kilojoules
Tip: To convert megajoules back to kilojoules, multiply by 1000.
Kilojoules to Megajoules
Convert kilojoules (kJ) to megajoules (MJ) with formulas, examples, and conversion tables.
kJ
MJ
1 kJ = 0.001 MJ
Full precision:0.001 MJ
Step-by-Step Solution
To convert 1 kilojoules to megajoules, we divide by 1000 because one megajoule equals exactly 1000 kilojoules.
1 megajoule = 1000 kilojoules
Since there are 1000 kilojoules in every megajoule, we divide our value by this factor:
1 ÷ 1000 = 0.001 megajoules
So 1 kilojoules = 0.001 megajoules.
Quick check: 0.001 × 1000 = 1 kilojoules
Example Conversions
Example 1: 1 kJ = 0.001 MJ
1 ÷ 1000 = 0.001
1 ÷ 1000 = 0.001
Example 2: 5 kJ = 0.005 MJ
5 ÷ 1000 = 0.005
5 ÷ 1000 = 0.005
Example 3: 10 kJ = 0.01 MJ
10 ÷ 1000 = 0.01
10 ÷ 1000 = 0.01
