Joule is the S.I unit and erg is C.G.S  of the energy.

Using  Dimensional formula of joule and erg:

⇒ n1(Joule) = n2(erg)

⇒ n1[M^{1}L^{2}T^{-2} ] = n2[M^{1}L^{2}T^{-2} ]

⇒ n1 = \frac{10[M^{1}L^{2}T^{-2} ]}{10^{-6} [M^{1}L^{2}T^{-2} ]}

⇒ n1= 10^{7}

☆Therefore:

  • 1 erg = 10^{7}Joule
  • 5 erg = 5×10^{7} Joule

Hence, 5 erg will be  5×10^{7}Joule.

Hope it Helps !!!
