Overview
SCFM (Standard Cubic Feet per Minute) is the flow rate of a gas corrected to 'standard' conditions of temperature and pressure. This allows for a fair comparison between different systems operating at different altitudes or temperatures.
💡
Pro Tips
Standard conditions typically use 14.7 psia for pressure and 60°F (520°R) for temperature.
Always use absolute pressure (psia) and absolute temperature (Rankine or Kelvin) in gas law calculations.
ACFM is the actual volume flow rate at the current operating temperature and pressure.

Fun Facts
"Compressed air is often called the 'fourth utility' after electricity, natural gas, and water."
"A typical air compressor takes about 7 to 8 cubic feet of air and compresses it into 1 cubic foot of tank space."
"SCFM is used by manufacturers to rate air tools so that users know exactly how much air they need regardless of where they are."
