How to Convert Liters per Second to m³/s
To convert liters per second to m³/s, multiply the flow rate by the following conversion ratio: 0.001 m³/s/liters per second.
Since one liters per second is equal to 0.001 m³/s, you can use this simple formula to convert:
The flow rate in m³/s is equal to the flow rate in liters per second multiplied by 0.001.
For example, here's how to convert 5 liters per second to m³/s using the formula above.
How Many m³/s Are in a Liters per Second?
There are 0.001 m³/s in a liters per second, which is why we use this value in the formula above.
Our liters per second to cubic meters 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 m³/s 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 Meters per Second?
A cubic meters per second is a unit of flow rate equal to 60,000 liters per minute (L/min), the base unit for flow rate. Coherent SI flow unit equal to 1,000 L/s (60,000 L/min). [2]
The cubic meters per second is classified as an International System of Units (SI) unit of flow rate. m³/s can be abbreviated as m³/s; for example, 1 cubic meters per second can be written as 1 m³/s.
When working with m³/s (m³/s) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, m³/s (m³/s) are widely used across large-scale industrial, bulk, and macro-level flow rate specifications within International System of Units (SI) workflows, engineering documentation, and technical data sheets.
When converting flow rate between liters per second (L/s) and m³/s (m³/s), keep full floating-point precision (1 L/s = 0.001 m³/s; 1 m³/s = 1,000 L/s) during intermediate calculations and round only the final cubic meters per second figure to match your instrument tolerance.
