To convert liters per second to cubic meters per hour, multiply by 3.6.
The calculation uses 1 L/s = 3.6 m³/h. Results are displayed to at most 10 significant digits. Definitions can be exact while a displayed decimal is rounded. Match the displayed precision to your original measurement.
The formula
value in m³/h = value in L/s × 3.6
L/s- Input unit: liters per second
m³/h- Output unit: cubic meters per hour
How to use this calculator
- Enter a value in L/s.
- Multiply by the stored conversion factor.
- Read the result in m³/h; divide by the same factor to convert back.
Worked examples
Worked conversion
1 L/s × 3.6 ≈ 3.6 m³/h.
Reverse conversion
3.6 m³/h ÷ 3.6 ≈ 1 L/s. Rounding intermediate values can change the last displayed digit.
Frequently asked questions
What factor does this converter use?
It uses 3.6 m³/h per L/s.
Why can another converter show a slightly different answer?
Check the unit convention first (such as US versus Imperial or decimal versus binary), then compare rounding. Measurement uncertainty is separate from the unit conversion.
