How to convert cubic meters per hour to liters per second
These are volumetric flow rates. US and Imperial gallons per minute differ; gas volumes quoted at standard conditions also need their reference temperature and pressure before comparison with actual flow.
L/s = m³/h × 0.2777777778One cubic meter per hour is 0.2777777778 liters per second, so a single multiplication converts any value.

Sources and precision
Table results are rounded to 8 significant digits; formula constants may be rounded to 10. Worked example answers use 6 significant digits. The converter starts at 6 significant digits and lets you change display precision. Calculations use the stored factors without intermediate rounding. Exact unit definitions do not make an input measurement more precise; conventional and measured factors follow the assumptions stated here.
