HRB to HRC Conversion Formula:
| From: | To: |
The HRB to HRC conversion provides an approximate conversion between Rockwell B and Rockwell C hardness scales. This empirical formula is useful for materials that fall between the measurement ranges of these two scales.
The calculator uses the empirical conversion formula:
Where:
Explanation: This empirical formula provides an approximate conversion between Rockwell B and C scales through an intermediate Brinell hardness calculation.
Details: Accurate hardness conversion is crucial for material selection, quality control, and comparing test results across different measurement scales in metallurgy and materials engineering.
Tips: Enter HRB hardness value between 0-100. The calculator will provide the approximate HRC equivalent. Note that this is an empirical approximation and may vary for specific materials.
Q1: Why convert between HRB and HRC?
A: Different materials are better suited to different Rockwell scales. Conversion allows comparison and material selection across the hardness spectrum.
Q2: How accurate is this conversion?
A: This is an empirical approximation. For precise conversions, consult material-specific conversion charts or standards.
Q3: What are typical HRB and HRC ranges?
A: HRB typically measures softer materials (0-100), while HRC measures harder materials (20-70). There's overlap in the middle range.
Q4: When should I use direct measurement instead of conversion?
A: For critical applications, always use direct measurement on the appropriate scale rather than relying on conversions.
Q5: Are there limitations to this conversion?
A: Yes, accuracy varies by material type, heat treatment, and specific alloy composition. Always verify with actual testing when precision is required.
