\mathrm{1\, MSD= \frac{1cm}{20}= 0.05\, cm}
\mathrm{10\, VSD= 9\, MSD}
\mathrm{Vernier\, constant= Least\, counct= 1MSD-1\, VSD}
                                                                     \mathrm{= 0.1\, MSD}

   \mathrm{Vernier\, constant=5\times 10^{-3}\, cm}
                                       \mathrm{=5\times 10^{-2}\, mm}
