Formula

Formula
m³/s = L/hr × 2.777778e-7

Multiply any value in litres per hour by 2.777778e-7 to obtain the value in cubic metres per second.

Worked example

Convert 1.00000e+6 L/hr to m³/s.

  1. 01Start with 1.00000e+6 L/hr.
  2. 02Multiply by the conversion factor: 1.00000e+6 × 2.777778e-7 = 0.277778 m³/s.
Result1.00000e+6 L/hr = 0.277778 m³/s

FAQ

What is the conversion factor from L/hr to m³/s?
1 L/hr equals 2.777778e-7 m³/s. To convert, multiply the value in litres per hour by 2.777778e-7.
How do I convert 1 L/hr to m³/s?
1 L/hr = 2.77778e-7 m³/s. For any value, multiply by 2.777778e-7.
How do I convert m³/s back to L/hr?
Divide by the same factor — or equivalently, multiply by 3600000. So 1 m³/s = 3.60000e+6 L/hr.
When would I need to convert litre per hour 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/hr to m³/s 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).
