This is usually measured in the Mohs scale of mineral hardness.
It measures 1-10, 1 being the softest, 10 the hardest.
Some examples of minerals classed 1-10:
1:Talc
2:Gypsum
3:Calcite
4:Flourite
5:Apatite
6:Orthoclase Feldspar
7:Quartz
8:Topaz
9:Corundum

Scratching a mineral with a nail is a test of hardness. The Mohs scale of mineral hardness ranks minerals from 1 (softest) to 10 (hardest), with talc being the softest and diamond being the hardest. If a mineral can be scratched by a nail (with a hardness of around 2.5), it would be classified as having a hardness lower than 2.5 on the Mohs scale.

One could purchase a used cat scratching post at a flea market, yard sale, or a swap meet. One could also check the classified advertisements in their local newspaper.
Cats see furniture as a scratching post, so, if you want to stop this behavior put more scratching posts, and pads in your house. If they still choose your furniture over the scratching post, try sprinkling the scratching posts with catnip.

Diamond is the hardest mineral and is the most resistant to scratching. Its hardness is assigned a value of 10 on the Mohs scale of mineral hardness, making it the top-ranked mineral in terms of scratch resistance.
Mineral hardness measures the resistance of a mineral to scratching or abrasion. It is determined by the ability of a mineral to scratch another mineral or be scratched by it, as defined by the Mohs scale of hardness.
It is called a streak and its purpose is to find the hardness of the mineral.
The ability of a mineral to hold together is known as its hardness. It is a measure of a mineral's resistance to scratching or abrasion. Hardness is determined by the strength of the atomic bonds within the mineral's crystal structure.
The scale that compares the resistance of the surfaces of minerals to scratching is called the Mohs scale of mineral hardness. It ranks minerals on a scale from 1 (softest) to 10 (hardest) based on their ability to scratch or be scratched by other minerals.
A mineral's resistance to being scratched (or when a force is applied) is called its hardness.There are different measurements of hardness: scratch hardness, indentation hardness, and rebound hardness. A material's hardness depends on ductility, elastic stiffness, plasticity, strain, strength, toughness, viscoelasticity, and viscosity.
The color of a mineral's powder found by scratching the mineral on a white tile is referred to as the mineral's streak color.
Scratching a mineral with a nail is a test of hardness. It helps determine the relative hardness of the mineral compared to known substances on the Mohs scale of mineral hardness.
Luster refers to the way light interacts with the surface of a mineral. Cleavage is the way a mineral breaks along planes of weakness. Hardness is the resistance of a mineral to scratching. Color is the visual appearance of a mineral, which can vary widely within the same mineral species.
This is diamond.
The resistance to being scratched is known as hardness. Hardness is a measure of how well a material can resist scratching or abrasion. It is commonly measured using the Mohs scale of mineral hardness.
The five properties of a mineral include color, streak, luster, hardness, and cleavage or fracture. Color is the visual appearance of the mineral, streak is the color of the mineral's powder, luster describes how the mineral reflects light, hardness measures the mineral's resistance to scratching, and cleavage or fracture describes how the mineral breaks.
