Convert between different hardness scales including Mohs, Rockwell, Vickers, and Brinell. Essential for materials science, metallurgy, and quality control.
Scientific and technical measurements
HRC (hard materials), HRB (softer materials), HRA (very hard materials)
Precise hardness testing using diamond pyramid and steel ball indenters
Mineral hardness scale from 1 (talc) to 10 (diamond)
Shore A (soft materials), Shore D (hard materials)
Hardness is a measure of a material's resistance to permanent deformation, particularly indentation. Different hardness testing methods use various indenters and loads, resulting in different scales that aren't directly comparable without conversion.
The Vickers hardness test uses a diamond pyramid indenter and is often used as a reference standard. Rockwell tests use different indenters and loads for different material ranges, while Brinell uses a steel ball indenter. The Mohs scale is qualitative and based on scratch resistance.
Our converter provides accurate conversions between these scales, accounting for the different testing methods and material properties. This is essential for comparing hardness values across different testing standards and selecting appropriate materials for specific applications.
Conversion Accuracy: Hardness conversions are approximate and depend on material properties.
Material Dependence: Different materials may have varying conversion factors.
Testing Conditions: Temperature, humidity, and testing conditions affect hardness values.
Standards: Always refer to official testing standards for critical applications.
