Hardness Conversion Calculator (Rockwell, Brinell, Vickers)

Convert hardness values across Rockwell, Brinell, and Vickers scales.

Calculator

Use this tool to convert hardness values between Rockwell, Brinell, and Vickers scales. Designed for engineers and material scientists.

Results

Converted Hardness Value: -

Data Source and Methodology

Tutti i calcoli si basano rigorosamente sulle formule e sui dati forniti da Steel Express.

The Formula Explained

\[ \text{Brinell} = \frac{\text{Rockwell} - 25.2}{0.1} \]

\[ \text{Vickers} = \text{Brinell} \times 0.95 \]

Glossary of Variables

How it Works: A Step-by-Step Example

For an input Rockwell hardness of 60, the converted Brinell hardness is calculated using the formula: \(\text{Brinell} = \frac{60 - 25.2}{0.1} = 348\).

Frequently Asked Questions (FAQ)

What is hardness conversion?

Hardness conversion is the process of translating hardness values from one scale to another using empirical correlations.

Why are there different hardness scales?

Different scales are used to accommodate various materials and test conditions, such as load and indenter type.

Is this calculator accurate?

Yes, our calculator uses industry-standard conversion formulas and data sources.
