How to Calculate LPM to LPS
To convert a flow rate from liters per minute (LPM) to liters per second (LPS), you divide the flow rate by 60. This is because there are 60 seconds in one minute. The mathematical formula for converting LPM to LPS is simple and easy to read:
Where:
- LPS: Liters per second, which represents the volumetric flow rate in SI units.
- LPM: Liters per minute, a common metric measurement for pump output and pipe flow.
Verified Calculation Example
Here is a step-by-step example showing how to convert a standard flow rate of 120 LPM to LPS:
- Given Flow Rate: 120 LPM
- Calculation:
LPS = 120 ÷ 60
- Result: LPS = 2
- Final Answer: 120 LPM is equivalent to 2 LPS.
Real-Life Applications
This flow rate conversion is widely used across various industries, including:
- Pump Sizing: Selecting commercial water pumps whose flow performance curves might be rated in liters per second (LPS) while system demands are defined in liters per minute (LPM).
- Water Treatment Systems: Calibrating chemical dosing pumps and measuring treatment plant throughput where chemical rates require sub-second precision.
- Irrigation Systems: Sizing pipelines and sprinkler outputs for agricultural fields to ensure correct water distribution volume.
- Fluid Flow Analysis: Performing hydraulic modeling and fluid mechanics calculations in piping systems where standard SI units (m³/s or L/s) are required.

Frequently Asked Questions (FAQs)
To convert a flow rate from liters per minute (LPM) to liters per second (LPS), you must divide the LPM value by 60. This is because there are exactly 60 seconds in one minute. This simple division gives you the flow rate over a much shorter time interval.
The basic mathematical formula for converting LPM to LPS is: LPS = LPM / 60. Alternatively, you can multiply the liters per minute value by 0.0166667. This conversion is highly useful when analyzing very fast flow rates in engineering and hydraulic systems.
If you have a flow rate of 100 liters per minute, dividing that number by 60 gives you approximately 1.667 liters per second. This calculation means that every single second, a volume of just over 1.6 liters is passing through the specific system or pipeline.
Liters per second (LPS) is frequently used in scientific research, hydrology, and advanced engineering to measure rapid, high-volume flows where analyzing second-by-second changes is critical. LPM is better suited for standard residential or commercial pumps.
Yes, liters per second is a recognized metric unit for measuring volumetric flow rate. While cubic meters per second (m³/s) is the official SI derived unit for flow rate, liters per second remains a practical and widely accepted measurement in many industries.
