Formula

Formula
L/s = m³/hr × 0.2777778

Multiply any value in cubic metres per hour by 0.2777778 to obtain the value in litres per second.

Worked example

Convert 100 m³/hr to L/s.

  1. 01Start with 100 m³/hr.
  2. 02Multiply by the conversion factor: 100 × 0.2777778 = 27.7778 L/s.
Result100 m³/hr = 27.7778 L/s

FAQ

What is the conversion factor from m³/hr to L/s?
1 m³/hr equals 0.2777778 L/s. To convert, multiply the value in cubic metres per hour by 0.2777778.
How do I convert 1 m³/hr to L/s?
1 m³/hr = 0.277778 L/s. For any value, multiply by 0.2777778.
How do I convert L/s back to m³/hr?
Divide by the same factor — or equivalently, multiply by 3.6. So 1 L/s = 3.6 m³/hr.
When would I need to convert cubic metre per hour 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/hr to L/s is a frequently needed conversion for hydraulic sizing.
Is the conversion exact?
Yes. Both m³/hr and L/s are defined by exact SI relationships, so the displayed factor is exact (any rounding shown is only for display).
