Ratings and Reviews
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.
Developer Response ,
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.
