How to Convert CFM to m³/h
To convert cfm to m³/h, multiply the flow rate by the following conversion ratio: 1.6990108 m³/h/cubic feet per minute.
Since one cubic feet per minute is equal to 1.6990108 m³/h, you can use this simple formula to convert:
The flow rate in m³/h is equal to the flow rate in cfm multiplied by 1.6990108.
For example, here's how to convert 100 cfm to m³/h using the formula above.
How Many m³/h Are in a Cubic Feet per Minute?
There are 1.6990108 m³/h in a cubic feet per minute, which is why we use this value in the formula above.
Our cubic feet per minute to cubic meters per hour calculator automatically converts your flow rate measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
CFM and m³/h are both units used to measure flow rate. Keep reading to learn more about each unit.
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). [1]
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.
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. [2]
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.
When converting flow rate between cfm (CFM) and m³/h (m³/h), keep full floating-point precision (1 CFM = 1.6990108 m³/h; 1 m³/h = 0.5885778 CFM) during intermediate calculations and round only the final cubic meters per hour figure to match your instrument tolerance.
