\(C.G.S.\) unit \(: gm\ c{m^{ - 1}}{\sec ^{ - 2}}\)

\(M.K.S.\) unit \(: kg.\ m^{-1}\ sec^{-2} .\)

\({n_2} = {n_1}{\left[ {\frac{{{M_1}}}{{{M_2}}}} \right]^1}{\left[ {\frac{{{L_1}}}{{{L_2}}}} \right]^{ - 1}}{\left[ {\frac{{{T_1}}}{{{T_2}}}} \right]^{ - 2}}\) \( = {\left[ {\frac{{gm}}{{kg}}} \right]^1}{\left[ {\frac{{cm}}{{meter}}} \right]^{ - 1}}{\left[ {\frac{{\sec }}{{\sec }}} \right]^{ - 2}}\)

\(\therefore \frac{{{n_2}}}{{{n_1}}} = {\left[ {\frac{{gm}}{{{{10}^3}gm}}} \right]^1}{\left[ {\frac{{cm}}{{{{10}^2}cm}}} \right]^{ - 1}}{\left[ {\frac{{\sec }}{{\sec }}} \right]^{ - 2}}\) \( = \frac{1}{{10}} = 0.1\)
