Estimated Hardness Equivalents between Vickers and Rockwell C
Please note the chart above is only intended to give a rough idea of the relationship between Vickers and Rockwell C hardness scales. It should not be used or relied upon to give accurate conversion. Much of the chart is impossible to actually practically verify by using the Rockwell C method.
Hardness Conversion or Equivalents:
Hardness conversion between different methods and scales cannot be made
mathematically exact for a wide range of materials. Different loads,
different shape of indenters, homogeneity of specimen, cold working
properties and elastic properties all complicate the problem. All
tables and charts should be considered as giving approximate
equivalents, particularly when converting to a method or scale which is
not physically possible for the particular test material and thus
cannot be verified. An example would be converting HV/10 or HR-15N
value on a thin coating to the HRC equivalent.
