Factor1 L/s = 127.1328 ft³/hr

Converter

L/s

Accepts numbers or expressions, e.g. 150 + 14.7

Result
127.133ft³/hr

Rendered to 6 significant figures.

Formula

Formula
ft³/hr = L/s × 127.1328

Multiply any value in litres per second by 127.1328 to obtain the value in cubic feet per hour.

Worked example

Convert 1 L/s to ft³/hr.

  1. 01Start with 1 L/s.
  2. 02Multiply by the conversion factor: 1 × 127.1328 = 127.133 ft³/hr.
Result1 L/s = 127.133 ft³/hr

FAQ

What is the conversion factor from L/s to ft³/hr?
1 L/s equals 127.1328 ft³/hr. To convert, multiply the value in litres per second by 127.1328.
How do I convert 1 L/s to ft³/hr?
1 L/s = 127.133 ft³/hr. For any value, multiply by 127.1328.
How do I convert ft³/hr back to L/s?
Divide by the same factor — or equivalently, multiply by 0.007865791. So 1 ft³/hr = 0.00786579 L/s.
When would I need to convert litre per second to cubic foot per hour?
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/hr 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).
