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/
