Converting between different hardness scales is not an exact science, but there are many charts available that will show the approximate relationship between different scales.
One chart is available at http://www.carbidedepot.com/formulas-hardness.htm
Another useful website for converting between different hardness scales is http://www.efunda.com/units/hardness/convert_hardness.cfm Tianxing Testing Instruments Co. Ltd. is a professional manufacturer of portable hardness testers http://www.hardnesstesters.biz/
Mohs hardness is not really convertible to Rockwell hardness. The hardness tested by the Mohs scale is the ability of a mineral to scratch or be scratched another mineral. Rockwell hardness is more for the testing of metals by an indenting probe under specific pressures.

You can't, you have to measure it or use an estimate off a table giving hardness numbers for various materials.
what is 60 rockwell c scale in mohs
You cannot
7
Rockwell hardness
Both are two different scales of hardness measurement.
plan a fair test with timing......... bash each rock with a hammer and see which one breaks first
No, because hardness is not a fundamental quality
it is 90
may be 75RHN

The initial load in Rockwell hardness test is 10KGf.
hardness as it is measured on a rockwell or brinell testing instrument
Rockwell hardness
The Rockwell C Hardness for a grade 10.9 fastener is 32 - 39HRC or 320 - 380Hv10
Both are two different scales of hardness measurement.
Rc is an abbreviation for the Rockwell Hardness Scale, used to determine the harness of materials.
