erg to kJ Converter - Erg to Kilojoule

Erg (erg) to Kilojoule (kJ)

Direct answer

1 erg = 1e-10 kJ

kJ = erg × 1e-10

Converter

Input

erg

Result

1e-10kJ

kJ = erg × 1e-10

erg = kJ × 1e+10

Example: 10 erg = 10 × 1e-10 = 1e-9 kJ.

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

1 erg = 1e-10 kJ.

10 erg = 1e-9 kJ.

100 erg = 1e-8 kJ.

Use kJ = erg × 1e-10.

1 kJ = 1e+10 erg.
