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.
