MJ to J Converter - Megajoule to Joule

Megajoule (MJ) to Joule (J)

Direct answer

1 MJ = 1,000,000 J

J = MJ × 1,000,000

Converter

Input

Result

1,000,000J

J = MJ × 1,000,000

MJ = J × 0.000001

Example: 10 MJ = 10 × 1,000,000 = 10,000,000 J.

Express both MJ and J in the same base unit J (joule), then cancel the shared base unit.

1
Rewrite MJ in the base unit
$1 MJ = 1, 000, 000 J$
2
Rewrite J in the base unit
$1 J = 1 J$
3
Forward conversion
$1 MJ = \frac{1 , 000 , 000 J}{1 J} \times 1 J = \frac{1 , 000 , 000}{1} J = 1, 000, 000 J$
4
Reverse conversion
$1 J = \frac{1 J}{1 , 000 , 000 J} \times 1 MJ = \frac{1}{1 , 000 , 000} MJ = 0.000001 MJ$

1 MJ = 1,000,000 J.

10 MJ = 10,000,000 J.

100 MJ = 100,000,000 J.

Use J = MJ × 1,000,000.

1 J = 0.000001 MJ.

Use the conversion factor and round the result to the precision required by your calculation.
