⭕️An erg is the amount of work done by a force of one dyne exerted for a distance of one centimeter.

❇️❇️❇️❇️❇️❇️❇️❇️❇️

⭕️ In the CGS base units, it is equal to one gram centimeter-squared per second-squared (g. cm2/s2). It is thus equal to 10−7 joules or 100 nanojoules (nJ) in SI units.

Unit of energy is joule = kg*m²/s²

Joule is a MKS unit and erg is a CGS unit

MKS = CGS

✔️1 m = 100 cm

✔️1 s = 1 s

✔️1 kg = 1000 gm

✔️From above :

✔️1 joule = 1 kg*m²/s² = 1000 * 10000 / 1 cm*m²/s²= 10^7 gm*cm²/s² = 10^7 erg

✔️So, Answer : 1 joule = 10^7 erg
