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