How to Convert CFH to mL/h
To convert cfh to ml/h, multiply the flow rate by the following conversion ratio: 28,316.846592 ml/h/cubic feet per hour.
Since one cubic feet per hour is equal to 28,316.846592 ml/h, you can use this simple formula to convert:
The flow rate in ml/h is equal to the flow rate in cfh multiplied by 28,316.846592.
For example, here's how to convert 5 cfh to ml/h using the formula above.
How Many mL/h Are in a Cubic Feet per Hour?
There are 28,316.846592 ml/h in a cubic feet per hour, which is why we use this value in the formula above.
Our cubic feet per hour 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.
CFH 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 Hour?
A cubic feet per hour is a unit of flow rate equal to 0.4719474 liters per minute (L/min), the base unit for flow rate. Gas meter flow unit (0.47195 L/min). [1]
The cubic feet per hour is classified as a US customary unit of flow rate. CFH can be abbreviated as CFH; for example, 1 cubic feet per hour can be written as 1 CFH.
When working with cfh (CFH) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, cfh (CFH) 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 cfh (CFH) and ml/h (mL/h), keep full floating-point precision (1 CFH = 28,316.846592 mL/h; 1 mL/h = 0.000035315 CFH) during intermediate calculations and round only the final milliliters per hour figure to match your instrument tolerance.
