Conversion Formula:
| From: | To: |
The HV to HRB conversion allows you to convert Vickers hardness values to Rockwell B hardness scale. This is useful when comparing material hardness measured using different testing methods or when specifications require values in a particular scale.
The calculator uses the conversion formula:
Where:
Explanation: This empirical formula provides an approximate conversion between Vickers and Rockwell B hardness scales based on established correlation data.
Details: Accurate hardness conversion is crucial for material specification compliance, quality control, and when comparing test results from different hardness testing methods in manufacturing and materials engineering.
Tips: Enter Vickers hardness value (HV) in the input field. The value must be greater than 0. The calculator will automatically compute the equivalent Rockwell B hardness (HRB).
Q1: How accurate is this conversion?
A: This conversion provides a good approximation for most common materials, but exact conversion may vary depending on material type and specific testing conditions.
Q2: What are typical HV and HRB ranges?
A: Vickers hardness typically ranges from 100-1000 HV, while Rockwell B typically ranges from 0-100 HRB, though both scales can extend beyond these ranges.
Q3: When should I use this conversion?
A: Use when you have Vickers hardness data but need Rockwell B values for specifications, comparisons, or reporting requirements.
Q4: Are there limitations to this conversion?
A: Conversion accuracy may be reduced for very high or very low hardness values, and for materials with unusual mechanical properties.
Q5: Can this conversion be used for all materials?
A: While generally applicable to most metals and alloys, specific materials may have slightly different conversion relationships.
