Hardness is a crucial property in materials science and engineering, and two common scales used to measure hardness are the Rockwell C (HRC) and Rockwell A (HRA) scales. HRC is typically used for measuring the hardness of steel, while HRA is used for softer materials like aluminum and brass. It’s important to understand the difference between these two scales when converting hardness values.
When converting hardness values from HRC to HRA, you need to consider the material being tested and the specific conversion chart for that material. The conversion chart will provide a formula or table to help you accurately convert the hardness values between the two scales.

How to Use an HRC to HRA Conversion Chart
To convert hardness values from HRC to HRA, you first need to determine the hardness value in HRC. Once you have this value, refer to the appropriate conversion chart for the material being tested. Follow the instructions on the chart to calculate the corresponding hardness value in HRA.
It’s important to note that the conversion between HRC and HRA is not a simple linear relationship, as the two scales measure hardness differently. The conversion chart takes into account the material properties and the specific testing conditions to provide an accurate conversion factor.
Conclusion
Converting hardness values from HRC to HRA is essential for comparing hardness values across different materials and scales. By using an HRC to HRA conversion chart, you can accurately convert hardness values and ensure consistency in your hardness testing results. Remember to always refer to the appropriate conversion chart for the specific material being tested to get the most accurate conversion.
