With a conversion table like you can see in this website :

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.
I don't found the Mohs hardness of technetium; probable was not measured. The Brinell hardness is 112 and the Vickers hardness is 151.
Aluminum oxide, as corundum, defines 9.0 on the Mohs hardness scale.
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.
flint is a type of quartz, so it has a hardness of about 7 on the mohs scale of hardness
what is the difference between Shore-A Hardness & Barcol Hardness
You don't convert Shore to Barcol or reverse. They aren't directly related, that's why you can't find any references for it. Shore D is a "softness" measure and Barcol is a "hardness" measure. The best bet is to go to the manufacturer of the product and ask directly for the number you need. They can easily test the material and give you an answer, but convert one to the other...you're asking for trouble.

It is estimated that the Vickers hardness of promethium is 617,8 MPa.
Minimum hardness of Mild steel is about 140 Vickers hardness.
The Brinell hardness of plutonium is 242, the Vickers hardness is 255.
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.
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.
The Brinell hardness of technetium is 112.The Vickers hardness of technetium is 151.
Plutonium is a silvery metal.- Vickers hardness: 255 - Brinell hardness: 242 - Mohs hardness: cca. 3,7
