How to Convert Liters per Second to cfs
To convert liters per second to cfs, multiply the flow rate by the following conversion ratio: 0.0353147 cfs/liters per second.
Since one liters per second is equal to 0.0353147 cfs, you can use this simple formula to convert:
The flow rate in cfs is equal to the flow rate in liters per second multiplied by 0.0353147.
For example, here's how to convert 5 liters per second to cfs using the formula above.
How Many cfs Are in a Liters per Second?
There are 0.0353147 cfs in a liters per second, which is why we use this value in the formula above.
Our liters per second to cubic feet per second calculator automatically converts your flow rate measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Liters per Second and cfs are both units used to measure flow rate. Keep reading to learn more about each unit.
What Is a Liters per Second?
A liters per second is a unit of flow rate equal to 60 liters per minute (L/min), the base unit for flow rate. Equal to 60 L/min. [1]
The liters per second is classified as a metric and SI-compatible unit of flow rate. Liters per Second can be abbreviated as L/s; for example, 1 liters per second can be written as 1 L/s.
When working with liters per second (L/s) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, liters per second (L/s) are widely used across standard flow rate applications within SI metric workflows, engineering documentation, and technical data sheets.
What Is a Cubic Feet per Second?
A cubic feet per second is a unit of flow rate equal to 1,699.0107955 liters per minute (L/min), the base unit for flow rate. River hydrology flow unit equal to 28.3168 L/s. [2]
The cubic feet per second is classified as a US customary unit of flow rate. cfs can be abbreviated as ft³/s; for example, 1 cubic feet per second can be written as 1 ft³/s.
When working with cfs (ft³/s) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, cfs (ft³/s) are widely used across large-scale industrial, bulk, and macro-level flow rate specifications within US customary workflows, engineering documentation, and technical data sheets.
When converting flow rate between liters per second (L/s) and cfs (ft³/s), keep full floating-point precision (1 L/s = 0.0353147 ft³/s; 1 ft³/s = 28.3168466 L/s) during intermediate calculations and round only the final cubic feet per second figure to match your instrument tolerance.
