Formula
Formula
L/s = ft³/min × 0.4719474
Multiply any value in cubic feet per minute by 0.4719474 to obtain the value in litres per second.
Worked example
Convert 100 ft³/min to L/s.
- 01Start with 100 ft³/min.
- 02Multiply by the conversion factor: 100 × 0.4719474 = 47.1947 L/s.
Result100 ft³/min = 47.1947 L/s

FAQ
What is the conversion factor from ft³/min to L/s?
1 ft³/min equals 0.4719474 L/s. To convert, multiply the value in cubic feet per minute by 0.4719474.
How do I convert 1 ft³/min to L/s?
1 ft³/min = 0.471947 L/s. For any value, multiply by 0.4719474.
How do I convert L/s back to ft³/min?
Divide by the same factor — or equivalently, multiply by 2.11888. So 1 L/s = 2.11888 ft³/min.
When would I need to convert cubic foot per minute to litre 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/min to L/s 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).
