How to Convert Cubic feet per second to Cubic feet per minute

Formula

To convert Cubic feet per second (ft³/s) to Cubic feet per minute (CFM): multiply by 60

Step-by-Step

  1. Start with your value in Cubic feet per second (ft³/s).
  2. Multiply by 60 to perform the conversion.
  3. The result is your value expressed in Cubic feet per minute (CFM).

Conversion Factor

1 ft³/s = 60 CFM

Reverse Factor

1 CFM = 0.0166667 ft³/s

Worked Example

Convert 25 Cubic feet per second to Cubic feet per minute: 25 ft³/s = 1500 CFM

About Cubic foot per second (ft³/s)

An imperial flow-rate unit used in US hydrology, river discharge measurement, and large-scale water-supply engineering. Also called "cusec" in water-resources jargon. Typical US river flow-rate reports (USGS streamgages) use cfs. A rainstorm runoff event in a small watershed might reach 100–500 cfs. 1 ft³/s = 7.48 gallons/second ≈ 28.3 L/s.

About Cubic foot per minute (CFM)

An imperial flow-rate unit dominant in US HVAC — air-handler capacity, duct sizing, bathroom/kitchen exhaust fan ratings, compressed-air-system sizing, and dust collection. A residential bathroom fan is typically 50–110 CFM; a central-AC air handler for a 2,000 ft² home delivers 800–1,200 CFM. Converting CFM to m³/hr (×1.699) is common for international HVAC equipment.
