Mohs measures relative hardness (quartz is harder than orthoclase; topaz is harder than quartz), but it doesn't accurately tell HOW MUCH harder something is than something else. There is another scale, called the Rockwell, which does this.

hardness
This scale is correctly called the Mohs scale. Scientists use this scale to measure a rock's hardness or softness. They can discover how hard a mineral or rocks is and drill in to it and find out more about it.
The Mohs scale is used to determine the relative hardness of minerals.
The scale used to measure the hardness of a rock is called the Mohs scale. It ranges from 1 (softest) to 10 (hardest) with each level representing a different mineral's ability to scratch another.
The Mohs scale is used to determine the relative hardness of minerals.
The Mohs scale is used to measure the hardness of minerals.
The Mohs Hardness Scale. PS: Talc is one of the softest minerals
Pure copper has a Mohs Hardness of 3. So called copper coins have a Mohs hardness of 3.2-3.5. Please see related links.
This scale was proposed by the Austrian geologist Friderich Mohs.
It's called the Ore
The Mohs scale. # Talc # Gypsum # Calcite # Fluorite # Apatite # Feldspar # Quartz # Topaz # Corundum # Diamond The Mohs scale, however, is an purely ordinal scale. For example, corundum (9) is twice as hard as topaz (8), but diamond (10) is almost four times as hard as corundum. Check the related link for more info.
