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
