I am trying to figure out how to convert mg/cubic meters to millions of particles/cubic feet. Can you help?

I was searching the OSHA website looking for the answer and it looks like you can't because mppcf is inaccurate, and measured in a different way from mg/m³
mg/m³ is a measurement of respirable mass dust concentration
mppcf is the count concentration.
