To determine the young's modulus of a wire , the formula is ` Y = (F)/( A) . (L)/ ( Delta l)` , where `L` = l ength ,` A`  = area of cross - section of the wire , `DeltaL` = change in the length of the wire when streched with a force `F`. Find the conversion factor to change it from CGS t o MKS system.
