Vickers microhardness for polished Cu specimen has been measured by conventional and new methods. The conventional microhardness was measured by observing the diagonal of indentation after the load was removed. Whereas, the new method for microhardness was obtained by measuring the penetration depth of indenter into the specimen under the load. As the applied load was increased, the microhardness obtained by new method was increased. When the applied load was in the range of 5mN to 80mN, the rate of elastic to total depth of indenter was about 6% and the calculated depth of rounded indenter was 0.07$mu extrm{m}$. The difference in microhardness measured by two different methods such as conventional and new methods can be explained in terms of the elastic deformation of specimen, the shape of practical indenter and pile up of material.
