Formula
Formula
ft³/min = L/s × 2.11888
Multiply any value in litres per second by 2.11888 to obtain the value in cubic feet per minute.
Worked example
Convert 1 L/s to ft³/min.
- 01Start with 1 L/s.
- 02Multiply by the conversion factor: 1 × 2.11888 = 2.11888 ft³/min.
Result1 L/s = 2.11888 ft³/min

FAQ
What is the conversion factor from L/s to ft³/min?
1 L/s equals 2.11888 ft³/min. To convert, multiply the value in litres per second by 2.11888.
How do I convert 1 L/s to ft³/min?
1 L/s = 2.11888 ft³/min. For any value, multiply by 2.11888.
How do I convert ft³/min back to L/s?
Divide by the same factor — or equivalently, multiply by 0.4719474. So 1 ft³/min = 0.471947 L/s.
When would I need to convert litre 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. L/s to ft³/min is a frequently needed conversion for hydraulic sizing.
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).
