How to Convert CFM to mL/h
To convert cfm to ml/h, multiply the flow rate by the following conversion ratio: 1,699,010.79552 ml/h/cubic feet per minute.
Since one cubic feet per minute is equal to 1,699,010.79552 ml/h, you can use this simple formula to convert:
The flow rate in ml/h is equal to the flow rate in cfm multiplied by 1,699,010.79552.
For example, here's how to convert 5 cfm to ml/h using the formula above.
How Many mL/h Are in a Cubic Feet per Minute?
There are 1,699,010.79552 ml/h in a cubic feet per minute, which is why we use this value in the formula above.
Our cubic feet per minute to milliliters 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 ml/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 Milliliters per Hour?
A milliliters per hour is a unit of flow rate equal to 1/60,000 of a liters per minute (0.000016667 L/min). Medical IV infusion pump rate unit. [2]
The milliliters per hour is classified as a metric and SI-compatible unit of flow rate. mL/h can be abbreviated as mL/h; for example, 1 milliliters per hour can be written as 1 mL/h.
In the metric system, "milli" is the standard SI prefix for thousandths, or 10⁻³. This makes the milliliters per hour (mL/h) a convenient decimal multiple of the liters per minute (L/min).
In practice, ml/h (mL/h) are widely used across fine-tolerance laboratory, analytical, and micro-scale flow rate measurements within SI metric workflows, engineering documentation, and technical data sheets.
When converting flow rate between cfm (CFM) and ml/h (mL/h), keep full floating-point precision (1 CFM = 1,699,010.79552 mL/h; 1 mL/h = 0.000000589 CFM) during intermediate calculations and round only the final milliliters per hour figure to match your instrument tolerance.
