1/16 inch diamond ball, 15 kgf load. The Rockwell Hardness Test presses a steel or diamond hemisphere-conical penetrator against a test specimen and measures the resulting indentation depth as a gage of the specimen hardness. The harder the material, the higher the HR reading.

It is impossible to define a single conversion method using different hardness test methods. That’s why these standards formulate tables for conversion process, with test load and hardness ranges. Here are the hardness tables and conversion charts for you.
Brinell and Rockwell Hardness Conversion Chart - These Conversion Tables presents data in the Rockwell A, B, C, D, E and F hardness range on the relationship among Brinell hardness, Vickers hardness, Rockwell and Shore Scleroscope hardness
The test measures the hardness by pressing an indentor into the surface of the steel with a specific load and them measuring how far the indentor was able to penetrate. HR15T can be represented as Rockwell Superficial 15-T Scale.
Convert hardness to equivalent hardness from different scales. Black and white version of conversion table for determining equivalent hardness for Rockwell, Rockwell Superficial, Vickers, Brinell, Scleroscope and ultimate tensile strength.
