How to Convert m³/s to CFM
To convert m³/s to cfm, multiply the flow rate by the following conversion ratio: 2,118.8800033 cfm/cubic meters per second.
Since one cubic meters per second is equal to 2,118.8800033 cfm, you can use this simple formula to convert:
The flow rate in cfm is equal to the flow rate in m³/s multiplied by 2,118.8800033.
For example, here's how to convert 5 m³/s to cfm using the formula above.
How Many CFM Are in a Cubic Meters per Second?
There are 2,118.8800033 cfm in a cubic meters per second, which is why we use this value in the formula above.
Our cubic meters per second to cubic feet per minute calculator automatically converts your flow rate measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
m³/s and cfm are both units used to measure flow rate. Keep reading to learn more about each unit.
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). [1]
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.
What Is a Cubic Feet per Minute?
A cubic feet per minute is a unit of flow rate equal to 28.3168466 liters per minute (L/min), the base unit for flow rate. HVAC & air compressor airflow unit (28.3168 L/min). [2]
The cubic feet per minute is classified as a US customary unit of flow rate. CFM can be abbreviated as CFM; for example, 1 cubic feet per minute can be written as 1 CFM.
When working with cfm (CFM) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, cfm (CFM) are widely used across standard flow rate applications within US customary workflows, engineering documentation, and technical data sheets.
When converting flow rate between m³/s (m³/s) and cfm (CFM), keep full floating-point precision (1 m³/s = 2,118.8800033 CFM; 1 CFM = 0.000471947 m³/s) during intermediate calculations and round only the final cubic feet per minute figure to match your instrument tolerance.
