FAQ

What is the conversion factor from cfs to mL/s?
1 cfs equals 28316.85 mL/s. To convert, multiply the value in cubic feet per second by 28316.85.
How do I convert 1 cfs to mL/s?
1 cfs = 28316.8 mL/s. For any value, multiply by 28316.85.
How do I convert mL/s back to cfs?
Divide by the same factor — or equivalently, multiply by 3.531467e-5. So 1 mL/s = 3.53147e-5 cfs.
When would I need to convert cubic foot per second to millilitre 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 mL/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).
