Formula

Formula
cfm = m³/s × 2118.88

Multiply any value in cubic metres per second by 2118.88 to obtain the value in cubic feet per minute.

Worked example

Convert 1 m³/s to cfm.

  1. 01Start with 1 m³/s.
  2. 02Multiply by the conversion factor: 1 × 2118.88 = 2118.88 cfm.
Result1 m³/s = 2118.88 cfm

FAQ

What is the conversion factor from m³/s to cfm?
1 m³/s equals 2118.88 cfm. To convert, multiply the value in cubic metres per second by 2118.88.
How do I convert 1 m³/s to cfm?
1 m³/s = 2118.88 cfm. For any value, multiply by 2118.88.
How do I convert cfm back to m³/s?
Divide by the same factor — or equivalently, multiply by 0.0004719474. So 1 cfm = 0.000471947 m³/s.
When would I need to convert cubic metre per second to cubic foot per minute?
Flow-rate conversions show up in pump curve interpretation, control valve sizing (Cv vs Kv), and aligning vendor specifications with process simulation outputs. m³/s to cfm is a frequently needed conversion for flow datasheet preparation.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
