Conversion???

[weldingsmith435]

Hi. My company recently bought a new Rofin Sinar 2kW Laser and I am helping create a spreadsheet that will show the combined cost of the new laser (maintenance, exhaust filter costs, etc...). I am currently having an issue with a conversion though my assist gas is rated in Cubic Feet per Hour (CFH) and my equation for the cost calls for Standard Cubic Feet per Hour (SCFH). I was wondering if anyone could help me with this dilemma.
