Vickers to Brinell Converter
HV → HB with the validity window every QA inspector should know.
Vickers stays linear to any hardness (diamond pyramid); Brinell saturates above ~450 (ball flattens). Above HV 450, convert to HRC instead — never to HB.
Formula
Note: Steel correlation; ±5% scatter is inherent to all hardness conversions.
Vickers to Brinell Converter is a free vickers to brinell for design engineers, metallurgists and QA inspectors — instant, accurate and 100% client-side, with the governing formula and reference shown next to the result so the number can be defended, not just quoted.
About Vickers to Brinell Converter
HV → HB with the validity window every QA inspector should know. The calculation implements HB ≈ 0.95·HV; both ≈ 3× yield in MPa-equivalent terms (ASTM E140; ISO 18265). Vickers stays linear to any hardness (diamond pyramid); Brinell saturates above ~450 (ball flattens). Above HV 450, convert to HRC instead — never to HB.

Frequently asked questions
What formula does the Vickers to Brinell Converter use?+
It computes HB ≈ 0.95·HV; both ≈ 3× yield in MPa-equivalent terms, per ASTM E140; ISO 18265. The formula is displayed under the result.
What should I keep in mind when using this calculator?+
Vickers stays linear to any hardness (diamond pyramid); Brinell saturates above ~450 (ball flattens). Above HV 450, convert to HRC instead — never to HB. Note: Steel correlation; ±5% scatter is inherent to all hardness conversions.
Where do the material property defaults come from?+
Defaults are standard handbook values (ASM, manufacturer datasheets, the cited standard). Always substitute certified values from your material's test certificate for critical work.
Is the Vickers to Brinell Converter free to use?+
Yes — completely free, no sign-up, no limits. It runs client-side in your browser, so inputs stay private and results are instant even on slow connections.
