Formula

Formula
cfm = mL/s × 0.00211888

Multiply any value in millilitres per second by 0.00211888 to obtain the value in cubic feet per minute.

Worked example

Convert 1000 mL/s to cfm.

  1. 01Start with 1000 mL/s.
  2. 02Multiply by the conversion factor: 1000 × 0.00211888 = 2.11888 cfm.
Result1000 mL/s = 2.11888 cfm

FAQ

What is the conversion factor from mL/s to cfm?
1 mL/s equals 0.00211888 cfm. To convert, multiply the value in millilitres per second by 0.00211888.
How do I convert 1 mL/s to cfm?
1 mL/s = 0.00211888 cfm. For any value, multiply by 0.00211888.
How do I convert cfm back to mL/s?
Divide by the same factor — or equivalently, multiply by 471.9474. So 1 cfm = 471.947 mL/s.
When would I need to convert millilitre 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. mL/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).
