설명

The Hardness Unit Converter application converts the hardness into 12 types of units.
The units to be converted by this application are Vickers hardness HV, Brinell hardness HBS, HBW, Rockwell hardness HRA, HRB, HRC, HRD, Rockwell superficial hardness HR 15 N, HR 30 N, HR 45 N, Shore hardness HS, and tensile strength MPa.
Simply input the hardness value and select the unit of hardness with the unit selection button, it will be converted into 12 types of units.
This application refers to the approximate conversion table of ASTM E 140 Table 1 and JIS, and data not in the table is calculated by polynomial approximation.

Wrong conversion?

So the interface is quite nice. The conversions aren’t the most accurate, but close. However, the wheels really come off the bus when conversting Vickers and Rockwell B. The app converts 160 HV to HRB as 81.7 (close), but when you enter 161 HV, it converts it to 116.7, and it gets worse from there.

Thank you for your advice.
As I confirmed here, it is true that the conversion formulas for Vickers and Rockwell B were wrong. I'm very sorry.
We are planning to release ver2.1.0 with modified conversion formulas for Vickers and Rockwell B in the near future.
We apologize for the inconvenience, but please update the app and check if it has been fixed when it is released.
