Factor1 m³/s = 1000 L/s

Converter

m³/s

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

Result
1000L/s

Rendered to 6 significant figures.

Formula

Formula
L/s = m³/s × 1000

Multiply any value in cubic metres per second by 1000 to obtain the value in litres per second.

Worked example

Convert 1 m³/s to L/s.

  1. 01Start with 1 m³/s.
  2. 02Multiply by the conversion factor: 1 × 1000 = 1000 L/s.
Result1 m³/s = 1000 L/s

FAQ

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