Hardness Converter Tool is designed to make convertions between most-used hardness data types. When you are on the home screen, you can quickly convert a value to others by clicking [Convert] button. Default input value type is set to Rockwell -Standart Brale 150 kg (C). However, you can change that when you get the convertion page by choosing the type you want over[Select Type] button on the home screen. If you want to see all values in the chart, select [View Table] on the home screen. You can make hardness convertions between these types: . Rockwell -Standart Brale 150 KG (C) . Rockwell -Standart Brale 60 KG (A) . Rockwell -Superficial Brale 15 KG (15-N) . Rockwell -Superficial Brale 30 KG (30-N) . Rockwell -Superficial Brale 45 KG (45-N) . Vickers -10 KG Diamond Pyramid . Tukon Knoop -500 gr & Over Diamond . Brinell -3000 KG 10 mm Ball . Tensile Strength -Approximately Kpsi .
