Vickers to Rockwell C
Type a value in HV to get it in HRC instantly.
58HRC
That's about the same as a good kitchen knife (HRC 58).
Convert the other way: HRC to HV
What it means
How hard is that?
For carbon and alloy steels (ASTM E140). Conversions between scales are approximate; for other metals and for exact values, test on the scale you need.
The math
How to convert HV to HRC
Hardness scales convert by table (ASTM E140): HRC 50 = 513 HV = 481 HB, HRC 40 = 392 HV = 371 HB. Tensile strength ≈ 3.45 × HB MPa.
Example: 653 HV = 58 HRC.
