Formula

Formula
m³/s = cfm × 0.0004719474

Multiply any value in cubic feet per minute by 0.0004719474 to obtain the value in cubic metres per second.

Worked example

Convert 1000 cfm to m³/s.

  1. 01Start with 1000 cfm.
  2. 02Multiply by the conversion factor: 1000 × 0.0004719474 = 0.471947 m³/s.
Result1000 cfm = 0.471947 m³/s

FAQ

What is the conversion factor from cfm to m³/s?
1 cfm equals 0.0004719474 m³/s. To convert, multiply the value in cubic feet per minute by 0.0004719474.
How do I convert 1 cfm to m³/s?
1 cfm = 0.000471947 m³/s. For any value, multiply by 0.0004719474.
How do I convert m³/s back to cfm?
Divide by the same factor — or equivalently, multiply by 2118.88. So 1 m³/s = 2118.88 cfm.
When would I need to convert cubic foot per minute to cubic metre per second?
Flow-rate conversions show up in pump curve interpretation, control valve sizing (Cv vs Kv), and aligning vendor specifications with process simulation outputs. cfm to m³/s 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).
