About Hardness Converter
The Hardness Converter converts between five hardness scales: Vickers (HV), Brinell (HB), Rockwell C (HRC), Rockwell B (HRB), and Shore (HS). It identifies your input's position on a reference conversion table and interpolates all compatible units from that position, delivering accurate and swift reference values.
Hardness scales do not have linear relationships, so values shown here are interpolated estimates based on representative ASTM E140-style conversion tables. Actual values depend on material, heat treatment, and test method. While useful for design reference, education, and rough comparison, use formal standards and measured values for production specifications and inspection.
