Frequently Asked Questions

Find Quick Answers

What is the accuracy of this HV to HRB conversion?

The conversion uses standard ASTM E140 hardness conversion tables for steel and other common metals, providing industry-standard accuracy within ±1 HRB for typical ranges.

Can I convert multiple HV values at once?

Yes, you can enter multiple comma-separated HV values (e.g., 150, 200, 250) or upload a CSV file with a column of HV values for bulk conversion.

What materials are supported for conversion?

Currently, the tool supports Steel (default), Aluminum, and Copper. The conversion formula adjusts based on material type to ensure accuracy.

Is there a limit to the number of values I can convert?

No, there is no hard limit. However, for performance reasons, extremely large datasets (e.g., over 10,000 values) may process slower in the browser.
