Formula
Formula
L/hr = L/s × 3600
Multiply any value in litres per second by 3600 to obtain the value in litres per hour.
Worked example
Convert 1 L/s to L/hr.
- 01Start with 1 L/s.
- 02Multiply by the conversion factor: 1 × 3600 = 3600 L/hr.
Result1 L/s = 3600 L/hr

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