A Rockwell hardness tester. The Rockwell scale is a hardness scale based on indentation hardness of a material. The Rockwell test measures the depth of penetration of an indenter under a large load (major load) compared to the penetration made by a preload (minor load). [1]
A variety of hardness-testing methods are available, including the Vickers, Brinell, Rockwell, Meyer and Leeb tests. Although it is impossible in many cases to give an exact conversion, it is possible to give an approximate material-specific comparison table for steels .

As such, hardness can only offer a comparative idea of the material's resistance to plastic deformation since different hardness techniques have different scales. The equation based definition of hardness is the pressure applied over the contact area between the indenter and the material being tested.

Donald Trump loved to use tariffs on foreign goods during his first presidency. “There's going to be a lot more tariffs, I mean, he's pretty clear,” said Michael Stumo, the CEO of Coalition ...
Two scales that measures rebound hardness are the Leeb rebound hardness test and Bennett hardness scale. Ultrasonic Contact Impedance (UCI) method determines hardness by measuring the frequency of an oscillating rod. The rod consists of a metal shaft with vibrating element and a pyramid-shaped diamond mounted on one end. [4]
