Formula
Formula
mL/s = L/s × 1000
Multiply any value in litres per second by 1000 to obtain the value in millilitres per second.
Worked example
Convert 1 L/s to mL/s.
- 01Start with 1 L/s.
- 02Multiply by the conversion factor: 1 × 1000 = 1000 mL/s.
Result1 L/s = 1000 mL/s

FAQ
What is the conversion factor from L/s to mL/s?
1 L/s equals 1000 mL/s. To convert, multiply the value in litres per second by 1000.
How do I convert 1 L/s to mL/s?
1 L/s = 1000 mL/s. For any value, multiply by 1000.
How do I convert mL/s back to L/s?
Divide by the same factor — or equivalently, multiply by 0.001. So 1 mL/s = 0.001 L/s.
When would I need to convert litre per second to millilitre 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/s to mL/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).
