Converter app with hardness values?

[kst8engineer]

I'm a new Droid owner, and being a mechanical engineer, I could use a good unit converter app that includes conversion of harness units (Vickers, Brinell, Rockwell, etc.). I've run across quite a few unit conversion apps, but without installing them, I don't know if they include hardness conversions.

Any recommendations?

Thanks
