1 ft³ = 0.028 316 8466 m³
N != S
"Normal" in Nm³ implies conditions of 273.15 K (0 °C) and 101.325 kPa. "Standard" in SCFH implies some standard temperature and the same pressure. Problem is, different industries use 15 °C, 60 °F, 20 °C, 75°F, 25 °C, and possibly others. Unless you know which standard temperature, SCFM is basically meaningless. If you find the temperature, convert to volume at 0 °C using Ideal Gas Law first, then convert to m³.

I've worked on technical documents that mention "standard" but didn't mention the basis for the standard.
Depending on which industry you're dealing with, the temperature can differ as mentioned above.
So you must know which temperature the standard is based on. You can assume, but you may get a different answer than what you're looking for. This is very crucial especially if you're selling gases to consumers.
If you can get hold of the mass flow, then I think it's easier to work on it to get the corresponding volume flow.

Re: convert scfh to ppm

1 PPM = 0.0001%
1000PPM = 1%
So now you have to mention your total flow of Valve so that we will easily decide for leakage.
percentage.
