# Convert mg/s to SCCM (Standard Cubic Centimeters per Minute)

1. Jun 15, 2017

Hello,

Can anyone explain the procedure to convert mg/s to SCCM?

I'm working with an Alicat Mass Flow Controller, which regulates Argon (Ar) mass flow from 1 to 6 mg/s at 27o C or 300 K (room temperature).

For documentation purpose, I need mass flow in terms of mg/s, as well as, SCCM.

Thank you

Hi,

mg/s is a mass flow and SSCM is a volume flow.
They are linked via the equation of state. For argon you can use the ideal gas law $pV = nRT$

Key is to find the proper standard conditions (confusion lurks, so be sure to mention them)
