The volume flow units, which contain "atm", assume that the gas is:
- ideal
- at a pressure of 101325 Pa
- at a temperature of 0 °C
Be aware that the unit "atm cm3/min", which is sometimes abbreviated "sccm" (standard cubic centimeter per minute), sometimes assumes a different temperature.
For approximating, remember that:
- 1 micromol/s ≈ 1.34 sccm ≈ 1 sccm
- 1 Torr ≈ 1.33 mbar ≈ 1 mbar
