MJ to erg Converter - Megajoule to Erg

Megajoule (MJ) to Erg (erg)

Direct answer

1 MJ = 1e+13 erg

erg = MJ × 1e+13

Converter

Input

Result

1e+13erg

erg = MJ × 1e+13

MJ = erg × 1e-13

Example: 10 MJ = 10 × 1e+13 = 1e+14 erg.

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

1 MJ = 1e+13 erg.

10 MJ = 1e+14 erg.

100 MJ = 1e+15 erg.

Use erg = MJ × 1e+13.

1 erg = 1e-13 MJ.

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