Convert ergs to joules

Explanation

From this page you can convert ergs to joules (or erg to J) simply, by using the application above.

In case you are wondering, to convert from ergs to joules you need to multiply by 0.0000001. This factor is calculated using the respective definitions of the two units you can find below.

Formula

1 erg=0.0000001 J

ergserg

dimension	energy
symbol	erg

The erg (erg) is a unit of energy. The unit was part of the CGS system.

Definition of the erg

One erg is the work done by a force of one dyne whose point of application moves one centimeter in the direction of the force.

Value in terms of the SI

One erg is equal to 10^-7 joules.

Equivalences

One erg is equivalent to:

≈ 624 gigaelectronvolts

Some Facts

The unit is still used today in radio astronomy. For example in chapter two of Essential Radio Astronomy, the Planck constant is expressed in erg⋅s (erg second) instead of J⋅H^-1 (joules per hertz).

Definition of the joule

Le joule est le travail produit par un newton dont le point d'application se déplace de un mètre dans la direction de la force.

9^th CGPM (1948) p. 113

That is to say, one joule is the work done by a force of one newton whose point of application moves one meter in the direction of the force.
