I need to figure out how to convert a concentration of a gas in PPM to a flow rate in SCCM. I know the gas, the pressure and am using a sniffer probe that reads in PPM.
Thanks!

You cannot convert concentration into flow rate without knowing the bulk flow rate and nature of the carrier gas at the prevailing flow pressure/temperature conditions.

Then don't forget to clearly establish what are the standard conditions of pressure and temperature the sniffer probe is using.
