1. What is Vickers to HRC Conversion?

The Vickers to Rockwell C (HRC) conversion provides an approximate equivalence between these two hardness scales. While exact conversion requires tables, this calculator uses a mathematical approximation for certain ranges.

2. How Does the Calculator Work?

The calculator uses the approximation formula:

Where:

• \( HV \) — Vickers hardness number (dimensionless)
• \( HRC \) — Rockwell C hardness number (dimensionless)

Note: This is an approximation. For precise conversions, consult official conversion tables.

3. Importance of Hardness Conversion

Details: Converting between hardness scales is important when comparing materials tested with different methods or when specifications require a particular scale.

4. Using the Calculator

Tips: Enter the Vickers hardness number (HV). The value must be positive. The result will be an approximate Rockwell C hardness value.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this conversion?
A: This provides a reasonable approximation for certain ranges, but for precise work, consult conversion tables.

Q2: What is the valid range for this conversion?
A: This approximation works best for HV values between 200 and 1000.

Q3: Why are there different hardness scales?
A: Different scales were developed for different materials and hardness ranges, each with its own advantages.

Q4: When should I use exact conversion tables?
A: For critical applications, material certifications, or when high precision is required.

Q5: Can I convert HRC back to HV with this?
A: No, this is a one-way approximation from HV to HRC only.
