Frequently Asked Questions
What units does this flow rate converter support?
Common units include liters per second, liters per minute, gallons per minute (GPM), and cubic meters per hour.
How do I convert GPM to liters per minute?
Multiply the GPM value by approximately 3.785 to get liters per minute.
What is flow rate used for?
Flow rate measures how much fluid or gas passes through a point over time — commonly used for pumps, plumbing, HVAC systems, and industrial process engineering.
Is this useful for sizing a water pump?
Yes — pump specifications are often listed in different flow rate units depending on the manufacturer's region, and this tool helps compare them directly.
Is this tool free to use?
Yes, completely free with no signup, no limits and no software to install.
Is my data saved anywhere?
No — conversions run in your browser and the values you enter are not stored or sent to a server.
What's a typical residential shower head flow rate?
Modern low-flow shower heads are often rated around 2 gallons per minute (about 7.6 liters per minute), a common reference point for plumbing flow rate discussions.
Is this useful for HVAC or irrigation system design?
Yes — airflow and water flow rate conversions are routine in HVAC ductwork sizing and irrigation system planning.
How many cubic meters per hour are in a liter per second?
One liter per second equals 3.6 cubic meters per hour.
Does this account for fluid viscosity or pressure differences?
No — this tool performs unit conversion only; actual flow rate in a real system also depends on pressure, pipe diameter, and fluid properties not covered by simple unit conversion.
