How it works

We use gpm = L/s x 15.8503231415.

Exact relationship: 1 L/s = 15.8503231415 gpm.

Example: 1 L/s = 15.850 gpm.

Notes: Results are rounded in the default view.

FAQ

What physical quantity do liters per second and gallons per minute express?

Liters per second express higher-rate metric flow more compactly than liters per minute for some engineering applications. Gallons per minute express volumetric flow rate, meaning how much volume moves over time rather than static capacity alone.

What is the difference between liters per second and gallons per minute?

Liters per second and gallons per minute both express volumetric flow rate, but they are favored in different liquid, air, utility, and process-system contexts.

What is the history of the liter per second?

Liters per second became common where SI-based flow reporting benefits from second-based rate calculations.

What is the history of the gallon per minute?

Gallons per minute grew from customary liquid-capacity practice and became standard in pumps, plumbing, and water-system work.

Were the liter per second and gallon per minute discovered by a specific person?

Liters per second are a standardized derived flow unit rather than something discovered by one person. Gallons per minute are a practical derived engineering unit rather than a one-person discovery.

Where are liters per second and gallons per minute used in science and engineering?

Liters per second are used in piping, civil utilities, process design, fire flow, and engineering calculations. Gallons per minute are used in pumps, water systems, coolant loops, irrigation, hydraulics, and utility flow discussions.

Why do flow-rate units matter in calculations?

Flow-rate units affect pump sizing, piping, ventilation, residence time, equipment selection, and process throughput. Keeping the unit attached helps avoid confusing static volume with volume per unit time.

Can I trust this for critical flow calculations?

Use this for convenience and verify against your governing standard, equipment curve, or controlled engineering source for critical work. Real systems still depend on pressure, temperature, losses, and operating conditions.
