Nano-indentation test is the most popular hardness testing method because it can correlate to other materials' mechanical properties and is used in a narrow area or for materials with plastic deformation resistance that Vickers hardness cannot represent. Linking the results of different hardness tests could provide flexibility in utilizing various hardness tests. Therefore, this research investigated the practical results of Vickers Microhardness and Berkovich Nano-indentation for three different materials. A mathematical model was applied to describe the Vickers hardness - Nano-indentation correlation based on the projected surface area resulting from indenter penetration. The results showed that Nano-hardness and Vickers hardness can be correlated. However, for the accuracy of the correlation, the precise measurement of the projected area must be considered. Ti6Al4V exhibited the largest differential between practical and theoretical Micro-hardness and Nano-hardness results, 43% and 37%, respectively, whereas copper had the lowest, 30% and 33%.
