Question

1 joule convert into erg​

Answer 1

Answer:

1 joule = 10^7 erg

Explanation:

1 joule = 1Newtonmeter

= 1 kgm^2/s^2

= 1 . 1000g . 10000 cm^2 / s^2

= 10^7 g cm^2 / s^2

= 10^7 erg

1 joule convert into erg

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

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

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
