Volumetric Flow Rate

L/stom³/s

Convert litres per second (L/s) to cubic metres per second (m³/s).

Factor1 L/s = 0.001 m³/s

Converter

L/s

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

Result
1m³/s

Rendered to 6 significant figures.

Formula

Formula
m³/s = L/s × 0.001

Multiply any value in litres per second by 0.001 to obtain the value in cubic metres per second.

Worked example

Convert 1000 L/s to m³/s.

  1. 01Start with 1000 L/s.
  2. 02Multiply by the conversion factor: 1000 × 0.001 = 1 m³/s.
Result1000 L/s = 1 m³/s

FAQ

What is the conversion factor from L/s to m³/s?
1 L/s equals 0.001 m³/s. To convert, multiply the value in litres per second by 0.001.
How do I convert 1 L/s to m³/s?
1 L/s = 0.001 m³/s. For any value, multiply by 0.001.
How do I convert m³/s back to L/s?
Divide by the same factor — or equivalently, multiply by 1000. So 1 m³/s = 1000 L/s.
When would I need to convert litre per second to cubic metre 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 m³/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).
