MJ
4 J = 4e-6 MJ
Full precision:0.000004 MJ
Step-by-Step Solution
To convert 4 joules to megajoules, we divide by 1000000 because one megajoule equals exactly 1000000 joules.
1 megajoule = 1000000 joules
Since there are 1000000 joules in every megajoule, we divide our value by this factor:
4 ÷ 1000000 = 4e-6 megajoules
So 4 joules = 4e-6 megajoules.
Quick check: 4e-6 × 1000000 = 4 joules
