erg to J Converter - Erg to Joule

Erg (erg) to Joule (J)

Direct answer

1 erg = 1e-7 J

J = erg × 1e-7

Converter

Input

erg

Result

1e-7J

J = erg × 1e-7

erg = J × 10,000,000

Example: 10 erg = 10 × 1e-7 = 0.000001 J.

Express both erg and J 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 J in the base unit
$1 J = 1 J$
3
Forward conversion
$1 erg = \frac{1 \times 1 0 ^{- 7} J}{1 J} \times 1 J = \frac{1 \times 1 0 ^{- 7}}{1} J = 1 \times 1 0^{- 7} J$
4
Reverse conversion
$1 J = \frac{1 J}{1 \times 1 0 ^{- 7} J} \times 1 erg = \frac{1}{1 \times 1 0 ^{- 7}} erg = 10, 000, 000 erg$

1 erg = 1e-7 J.

10 erg = 0.000001 J.

100 erg = 0.00001 J.

Use J = erg × 1e-7.

1 J = 10,000,000 erg.

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