Convert flow rate between milliliters per second, liters per second, liters per minute, liters per hour, cubic meters per second, cubic meters per hour, cubic feet per second, and US gallons per minute. Zero is a valid flow rate.
Conversions run locally in your browser; your flow rate is not uploaded or stored.
Convert one flow rate into the units you need.
Enter a non-negative flow rate and choose its unit to see the equivalent milliliters per second, liters per second, liters per minute, liters per hour, cubic meters per second, cubic meters per hour, cubic feet per second, and US gallons per minute.

Frequently Asked Questions
Everything you need to know about this tool, how it works, and privacy.
Which flow rate units can I convert?
Enter a flow rate in milliliters per second, liters per second, liters per minute, liters per hour, cubic meters per second, cubic meters per hour, cubic feet per second, or US gallons per minute. The converter returns the equivalent value in all eight units using 1 L/s = 1000 mL/s, 1 L/min = 1/60 L/s, 1 m3/s = 1000 L/s, 1 ft3/s = 28.316846592 L/s, and 1 GPM = 3.785411784/60 L/s.
Can I convert zero or decimal flow rate values?
Yes. Zero is a valid flow rate, and decimal values are accepted. Negative values are rejected because a flow rate magnitude cannot be less than zero. Results show up to six decimal places when needed.
What happens with very large flow rate values?
The converter shows an error when the entered flow rate is too large to convert safely, instead of returning an unreliable rounded result.
Does my flow rate leave my browser?
No. The conversion and copy action run locally in your browser. CodeASystem does not upload or store the value you enter.
