Yogita Ingle 5 years, 1 month ago

1 kg = 10³ g

1 m² = 10⁴ cm²

1 kg m² s^–2 = 1 kg × 1 m² × 1 s^–2

=10³g × 10⁴ cm² × 1 s^–2 = 10⁷ g cm² s^–2

1 kg m²s^–2 = 10⁷ g cm² s^–2

Yogita Ingle 5 years, 1 month ago

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
