kovuusasteina
Kovuusasteina is a term that refers to a scale used to measure the hardness of materials. Specifically, it denotes a set of hardness scales that are often employed in fields such as geology, materials science, and manufacturing. The most well-known of these scales is the Mohs scale of mineral hardness, which ranks minerals based on their ability to scratch one another. On the Mohs scale, softer minerals are scratched by harder ones, establishing a relative order of hardness.
While the Mohs scale is a common reference point, other hardness scales exist, each with its own
