How to Convert mL/h to CFM
To convert ml/h to cfm, multiply the flow rate by the following conversion ratio: 0.000000589 cfm/milliliters per hour.
Since one milliliters per hour is equal to 0.000000589 cfm, you can use this simple formula to convert:
The flow rate in cfm is equal to the flow rate in ml/h multiplied by 0.000000589.
For example, here's how to convert 5 ml/h to cfm using the formula above.
How Many CFM Are in a Milliliters per Hour?
There are 0.000000589 cfm in a milliliters per hour, which is why we use this value in the formula above.
Our milliliters 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.
mL/h and cfm are both units used to measure flow rate. Keep reading to learn more about each unit.
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. [1]
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.
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 ml/h (mL/h) and cfm (CFM), keep full floating-point precision (1 mL/h = 0.000000589 CFM; 1 CFM = 1,699,010.79552 mL/h) during intermediate calculations and round only the final cubic feet per minute figure to match your instrument tolerance.
