Formula

Formula
m³/s = cfs × 0.02831685

Multiply any value in cubic feet per second by 0.02831685 to obtain the value in cubic metres per second.

Worked example

Convert 100 cfs to m³/s.

  1. 01Start with 100 cfs.
  2. 02Multiply by the conversion factor: 100 × 0.02831685 = 2.83168 m³/s.
Result100 cfs = 2.83168 m³/s

FAQ

What is the conversion factor from cfs to m³/s?
1 cfs equals 0.02831685 m³/s. To convert, multiply the value in cubic feet per second by 0.02831685.
How do I convert 1 cfs to m³/s?
1 cfs = 0.0283168 m³/s. For any value, multiply by 0.02831685.
How do I convert m³/s back to cfs?
Divide by the same factor — or equivalently, multiply by 35.31467. So 1 m³/s = 35.3147 cfs.
When would I need to convert cubic foot per second 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. cfs 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).
