Volumetric Flow Rate

L/hrtom³/hr

Convert litres per hour (L/hr) to cubic metres per hour (m³/hr).

Factor1 L/hr = 0.001 m³/hr

Converter

L/hr

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

Result
1m³/hr

Rendered to 6 significant figures.

Formula

Formula
m³/hr = L/hr × 0.001

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

Worked example

Convert 1000 L/hr to m³/hr.

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

FAQ

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