Joule is the unit for energy
Dimension Formula for Joule is [M¹L²T⁻²]
Let n1(joule)=n2(erg)
n1(M₁¹L₁²T₁⁻²]=n2[M₂¹L₂²T₂⁻²]
n2=n1(M₁¹L₁²T₁⁻²] /M₂¹L₂²T₂⁻²]
=n1x(M1/M2)¹x(L1/L2)²x(T1/T2)⁻²
=1x(1kg/gm)¹x(1m/1cm)²x(1s/1s)⁻²
=1x(1000g/gm)x(100cm/1cm)²x(1s/1s)⁻²
=10⁷
Therefore n1(joule)=n2(erg)
∴1 Joule=10⁷erg
