Factor1 L/hr = 9.80963e-6 cfs

Converter

L/hr

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

Result
0.980963cfs

Rendered to 6 significant figures.

Formula

Formula
cfs = L/hr × 9.80963e-6

Multiply any value in litres per hour by 9.80963e-6 to obtain the value in cubic feet per second.

Worked example

Convert 100000 L/hr to cfs.

  1. 01Start with 100000 L/hr.
  2. 02Multiply by the conversion factor: 100000 × 9.80963e-6 = 0.980963 cfs.
Result100000 L/hr = 0.980963 cfs

FAQ

What is the conversion factor from L/hr to cfs?
1 L/hr equals 9.80963e-6 cfs. To convert, multiply the value in litres per hour by 9.80963e-6.
How do I convert 1 L/hr to cfs?
1 L/hr = 9.80963e-6 cfs. For any value, multiply by 9.80963e-6.
How do I convert cfs back to L/hr?
Divide by the same factor — or equivalently, multiply by 101940.6. So 1 cfs = 101941 L/hr.
When would I need to convert litre per hour to cubic foot 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. L/hr to cfs 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).
