erg to MJ Converter - Erg to Megajoule

Erg (erg) to Megajoule (MJ)

Direct answer

1 erg = 1e-13 MJ

MJ = erg × 1e-13

Converter

Input

erg

Result

1e-13MJ

MJ = erg × 1e-13

erg = MJ × 1e+13

Example: 10 erg = 10 × 1e-13 = 1e-12 MJ.

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

1
Rewrite erg in the base unit
$1 erg = 1 \times 1 0^{- 7} J$
2
Rewrite MJ in the base unit
$1 MJ = 1, 000, 000 J$
3
Forward conversion
$1 erg = \frac{1 \times 1 0 ^{- 7} J}{1 , 000 , 000 J} \times 1 MJ = \frac{1 \times 1 0 ^{- 7}}{1 , 000 , 000} MJ = 1 \times 1 0^{- 13} MJ$
4
Reverse conversion
$1 MJ = \frac{1 , 000 , 000 J}{1 \times 1 0 ^{- 7} J} \times 1 erg = \frac{1 , 000 , 000}{1 \times 1 0 ^{- 7}} erg = 1 \times 1 0^{13} erg$

1 erg = 1e-13 MJ.

10 erg = 1e-12 MJ.

100 erg = 1e-11 MJ.

Use MJ = erg × 1e-13.

1 MJ = 1e+13 erg.

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