How to Convert m³/h to CFM
To convert m³/h to cfm, multiply the flow rate by the following conversion ratio: 0.5885778 cfm/cubic meters per hour.
Since one cubic meters per hour is equal to 0.5885778 cfm, you can use this simple formula to convert:
The flow rate in cfm is equal to the flow rate in m³/h multiplied by 0.5885778.
For example, here's how to convert 5 m³/h to cfm using the formula above.
How Many CFM Are in a Cubic Meters per Hour?

Our cubic meters per hour 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/h and cfm are both units used to measure flow rate. Keep reading to learn more about each unit.
What Is a Cubic Meters per Hour?
A cubic meters per hour is a unit of flow rate equal to 16.6666667 liters per minute (L/min), the base unit for flow rate. Equal to 16.6667 L/min. [1]
The cubic meters per hour is classified as a metric and SI-compatible unit of flow rate. m³/h can be abbreviated as m³/h; for example, 1 cubic meters per hour can be written as 1 m³/h.
When working with m³/h (m³/h) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, m³/h (m³/h) are widely used across standard flow rate applications within SI metric 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/h (m³/h) and cfm (CFM), keep full floating-point precision (1 m³/h = 0.5885778 CFM; 1 CFM = 1.6990108 m³/h) during intermediate calculations and round only the final cubic feet per minute figure to match your instrument tolerance.
