How to convert liters per second to US gallons per minute
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.
gpm = L/s × 15.85032314One liter per second is 15.85032314 US gallons per minute, so a single multiplication converts any value.
158.503 gpm ≈ 10 × 15.85032314Liters per second to US gallons per minute conversion table

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.
