The author has proposed the new measuring method with Rockwell hardness which is measured by indenter with a conical angle different from 120° or by the larger initial load than 10 kg. The conversion formulae between these hardnesses and Vickers hardness H_v and the equations of errors were induced theoretically and checked experimentally. These new hardnesses have many merits. For examples, using the 1arger conical angle than 120°, the hardness range of 60<H_v<1000 can be expressed by a single indenter continuously and the thin sheets are measured without employing special superficial tester. The smaller conical angle than 120° is effective to raise the sensitiveness of measurement for very hard specimens. For rough surfaces, we can get the reliable results which have very small scattering ranges by larger initial load.
