Formula

Formula
mL/s = ft³/hr × 7.865791

Multiply any value in cubic feet per hour by 7.865791 to obtain the value in millilitres per second.

Worked example

Convert 1 ft³/hr to mL/s.

  1. 01Start with 1 ft³/hr.
  2. 02Multiply by the conversion factor: 1 × 7.865791 = 7.86579 mL/s.
Result1 ft³/hr = 7.86579 mL/s

FAQ

What is the conversion factor from ft³/hr to mL/s?
1 ft³/hr equals 7.865791 mL/s. To convert, multiply the value in cubic feet per hour by 7.865791.
How do I convert 1 ft³/hr to mL/s?
1 ft³/hr = 7.86579 mL/s. For any value, multiply by 7.865791.
How do I convert mL/s back to ft³/hr?
Divide by the same factor — or equivalently, multiply by 0.1271328. So 1 mL/s = 0.127133 ft³/hr.
When would I need to convert cubic foot per hour 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. ft³/hr 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).
