Cubic Foot per Minute to Cubic Meter per Day (CFM to m³/d)
Convert CFM to m³/d — Flow Rate converter
Also written as CFM to m3/d.
One cubic foot per minute equals 40.776259 m³/d, so to convert cubic feet per minute to cubic meters per day you multiply the value by 40.776259. A cubic foot per minute is larger than a cubic meter per day — going the other way, 1 m³/d = 0.02452407 CFM. For example, 10 CFM = 407.762591 m³/d and 50 CFM = 2038.81 m³/d.
1 CFM = 40.776259 m³/d
Cubic Foot per Minute to Cubic Meter per Day formula
1 Cubic Foot per Minute = 40.776259 m³/d
Worked examples
- 25 CFM = 1019.41 m³/d
- 100 CFM = 4077.63 m³/d

Which gallon, and which trade
The single most expensive mistake in flow conversion is the gallon. A US liquid gallon is 3.785411784 litres; an imperial gallon is 4.54609 litres. US GPM and imperial GPM differ by about 20%, and pump datasheets frequently do not say which one they mean. Check the manufacturer's country of origin before trusting a GPM figure.
Different trades default to different units for the same physical quantity: HVAC and compressed air work in CFM, plumbing and pumps in GPM or LPM, and process and water engineering in m³/h or L/s. A specification that mixes them is usually quoting different equipment, not different flows. On this page, 1 CFM = 40.776259 m³/d.
CFM to metric is worth memorising: one cubic foot is exactly 0.028316846592 m³, so 1 CFM = 1.699011 m³/h and 1,000 CFM ≈ 1,699 m³/h. Note that CFM on a compressor may be quoted as free air delivery (FAD) at inlet conditions rather than at working pressure — the two are not interchangeable.
