Questions and answers on how to convert things from one unit or system to another
Forum rules
Dear convert-me.com forum visitors,

Our forum has been available for many years. In September 2014 we decided to switch it to read-only mode. Month after month we saw less posts with questions and answers from real people and more spam posts. We were spending more and more resources cleaning the spam until there were less them 1 legitimate message per 100 spam posts. Then we decided it's time to stop.

All the posts in the forum will be available and searchable. We understand there are a lot of useful information and we aren't going to remove anything. As for the new questions, you can always ask them on convert-me.com FaceBook page

Thank you for being with us and sorry for any inconveniences this could caused.

How do you convert from cubic feet per minute to standard cubic feet per minute.

Ideal gas law.

CFM is measured at actual temperature and pressure. SCFM is volume adjusted by ideal gas law to a reference temperature and pressure. The reference pressure is almost certainly 1 atm, 101.325 kPa. The temperature varies by gas and by industry, 15 C, 20 C, 60 F, and 70 F are all used. (In ideal gas law, be sure to convert the temperature to absolute, either kelvin or Rankine depending on which units you are using.
