Well, honey, converting Barcol hardness to Vickers hardness ain't exactly a walk in the park. You'll need to consult some fancy conversion charts or formulas to make that happen. It's not as simple as snapping your fingers, but with a little bit of elbow grease, you'll get there.
I don't found the Mohs hardness of plutonium but: - the Brinell hardness is 242 at r.m. - the Vickers hardness is 255 at r.m. After a hardness conversion chart an equivalent Mohs hardness may be 3,7.
Aluminum oxide, as corundum, defines 9.0 on the Mohs hardness scale.
Technetium is relatively rare, with an atomic number of 43. In terms of hardness, it does not have a defined ranking on the Mohs scale, which is typically used to measure the hardness of minerals from 1 (softest) to 10 (hardest).
The hardness of a mineral is determined by its resistance to scratching. The most commonly used method to measure hardness is the Mohs scale, which ranks minerals from 1 (softest) to 10 (hardest) based on their ability to scratch each other. Another method is the Vickers hardness test, which measures the resistance of a mineral to indentation using a diamond indenter.
Marble ranges from 2-5 on Moh's scale.add. There are several hardness scales other than Mohs, which is an arbitrary scale of hardness. .There is a Janka scale for wood, but be careful of the units used.There is a Rockwell scale for the Hardness of steel. This measurement leaves little mark (impression).There is a Brinell hardness scale which forces a hard steel ball into the test piece. This method leaves an impression on the test piece, but can be calibrated for steel, wood, and other metals.The Vickers Hardness test uses a diamond indenter, and is often used for hard materials such as case-hardened material.[Rockwell, Brinell, and Vickers have tables of equivalence.]And, last of all is a hardness test for paints and similar. This test, BS3900 - E19, ISO 15184, uses ordinary pencils of various hardness to determine the hardness of the paint film.
what is the difference between Shore-A Hardness & Barcol Hardness
The formula to convert Vickers to Brinell hardness is: Brinell Hardness = (2.025 x Vickers Hardness).
Oh, dude, converting Barcol hardness to Shore D hardness is like trying to turn a pineapple into a watermelon. You can't just snap your fingers and make it happen. You'll need to consult some conversion tables or equations to make that magic work. Good luck with that, my friend!

It is estimated that the Vickers hardness of promethium is 617,8 MPa.
Minimum hardness of Mild steel is about 140 Vickers hardness.
HV = 2.9 * Y Where HV - Vickers hardness Y - Yiekd stress in KG/mm2
The Brinell hardness of technetium is 112.The Vickers hardness of technetium is 151.

In Vickers hardness test the for used is much lighter than the force used in Rockwell hardness test, The Rockwell hardness test is the considered to be the most routinely used technique to measure the hardness of materials because of its simplicity and because it does not require specific skills in order to perform it.
Vickers is only used for metals (far as I can tell). As for the values you wish to find, look on Mindat.org
