Flow Rate Converter
Liters/minute (L/min)
Definition: Liters per minute (symbol: L/min or LPM) is a metric unit of volumetric flow rate that measures the volume of a fluid (one liter) passing a specific point in one minute.
History/origin: This unit is a direct combination of the metric unit for volume (the liter) and the universal unit of time (the minute). It was adopted for practical everyday flow measurements.
Current use: LPM is widely used to measure water flow in household plumbing (faucets, showers), medical oxygen delivery systems, and laboratory liquid pumps.
Liters/second (L/s)
Definition: Liters per second (symbol: L/s) is a unit of volumetric flow rate representing one liter of fluid moving past a point every second.
History/origin: Derived directly from the International System of Units (SI) standards, combining the non-SI but accepted liter with the SI base unit of time (the second).
Current use: This unit is commonly used in hydrology to measure stream and river flows, civil engineering for drainage systems, and industrial water pumping.

How to Convert Liters/minute (L/min) to Liters/second (L/s)
1 lpm = 0.01666667 lps
1 lps = 60 lpm
Example: convert 15 lpm to lps:
15 lpm = 15 × 0.01666667 lps = 0.25 lps
Did You Know?
- A standard modern showerhead uses about 9.5 Liters per minute (L/min) to save water, whereas older ones used up to 20 L/min!
- At rest, an average adult human breathes at a flow rate of about 0.1 Liters per second (L/s), which equals about 6 Liters per minute.
