convert 1 erg into joule

$\bold{\huge\blue{\boxed{{{Answer}}}}}$

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, 1 joule = 10^7 erg
