SCFM refers to "standard cubic feet per minute" or the given flow rate of air at standard room temperature and pressure. Standard air flow is the baseline required flow; depending on your operating conditions (i.e. differing pressure and temperature) this tool allows you to convert the required SCFM, to the actual flow or ACFM that you will read from your instruments.
