Factor1 L/hr = 0.0002777778 L/s
Converter
L/hr
Accepts numbers or expressions, e.g. 150 + 14.7
Result
L/s
Rendered to 6 significant figures.
Formula
Formula
L/s = L/hr × 0.0002777778
Multiply any value in litres per hour by 0.0002777778 to obtain the value in litres per second.
Worked example
Convert 3600 L/hr to L/s.
- 01Start with 3600 L/hr.
- 02Multiply by the conversion factor: 3600 × 0.0002777778 = 1 L/s.
Result3600 L/hr = 1 L/s

FAQ
What is the conversion factor from L/hr to L/s?
1 L/hr equals 0.0002777778 L/s. To convert, multiply the value in litres per hour by 0.0002777778.
How do I convert 1 L/hr to L/s?
1 L/hr = 0.000277778 L/s. For any value, multiply by 0.0002777778.
How do I convert L/s back to L/hr?
Divide by the same factor — or equivalently, multiply by 3600. So 1 L/s = 3600 L/hr.
When would I need to convert litre per hour 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. L/hr 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).
