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.
Each of the ten hardness values in the Mohs scale is represented by a reference mineral, most of which are widespread in rocks. The Mohs scale is an ordinal scale . For example, corundum (9) is twice as hard as topaz (8), but diamond (10) is four times as hard as corundum.
The three tables should be united into one, with side-by-side Vickers, Brinell, Rockwell and megapascal values. 82.131.210.162 10:47, 16 June 2008 (UTC) []. Yes, done. Values should be taken as very approxi

Suffice to say Dejounte Murray enjoyed his first game in a New Orleans Pelicans uniform a lot more than his long-awaited second. Boos rained down from a large and initially lively Thanksgiving eve ...
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]
