How to Convert Cubic Meter per Hour to Liter per Second
- 1 m³/h = 0.2777777778 L/s
- 1 L/s = 3.6 m³/h
- Example: convert 15 m³/h to L/s: 15 m³/h = 15 × 0.2777777778 L/s = 4.166666667 L/s
Formula
L/s = m³/h × 0.2777777777778
or L/s = m³/h ÷ 3.6
Derivation from SI units:
- 1 m³/h = 1 m³ ÷ 3600 s
- 1 L/s = 10⁻³ m³ ÷ 1 s
- 1 m³/h = 0.0002777777777778 m³/s ÷ 0.001 m³/s per L/s = 0.2777777777778 L/s
Both units are defined exactly, so the factor is exact. Cubic Meter per Hour definition: cubic meter per hour; Liter per Second definition: liter per second.
Worked examples
- 360 m³/h is exactly 100 L/s.
360 m³/h × 0.2777777778 = 100 L/s - A filter rated at 3400 m³/h carries 944.4444444 L/s.
3400 m³/h × 0.2777777778 = 944.4444444 L/s

Frequently asked questions
How do I convert m³/h to L/s?
Divide by 3.6: 900 m³/h = 250 L/s.
How many liters per second are in 1 cubic meter per hour?
1 m³/h = 0.2777777778 L/s.
How do I convert cubic meters per hour to liters per second?
Multiply the value in m³/h by 0.2777777778, or divide it by 3.6. For example, 15 m³/h × 0.2777777778 = 4.166666667 L/s.
Is the m³/h to L/s conversion exact?
Yes. Both units are defined exactly, so the ratio is exact; its decimal form does not terminate and is shown here to 10 significant figures (more with the precision selector).
