FAQ

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