Flow Rate Converter
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.
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) to Liters/minute (L/min) Conversion Table
| Liters/second (L/s) [lps] | Liters/minute (L/min) [lpm] |
|---|---|
| 0.01 lps | 0.6 lpm |
| 0.1 lps | 6 lpm |
| 1 lps | 60 lpm |
| 2 lps | 120 lpm |
| 3 lps | 180 lpm |
| 5 lps | 300 lpm |
| 10 lps | 600 lpm |
| 20 lps | 1200 lpm |
| 50 lps | 3000 lpm |

How to Convert Liters/second (L/s) to Liters/minute (L/min)
1 lps = 60 lpm
1 lpm = 0.01666667 lps
Example: convert 15 lps to lpm:
15 lps = 15 × 60 lpm = 900 lpm
Did You Know?
- 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.
- 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!
