How to Convert mL/h to cfs
To convert ml/h to cfs, multiply the flow rate by the following conversion ratio: 9.80963e-9 cfs/milliliters per hour.
Since one milliliters per hour is equal to 9.80963e-9 cfs, you can use this simple formula to convert:
The flow rate in cfs is equal to the flow rate in ml/h multiplied by 9.80963e-9.
For example, here's how to convert 5 ml/h to cfs using the formula above.
How Many cfs Are in a Milliliters per Hour?
There are 9.80963e-9 cfs in a milliliters per hour, which is why we use this value in the formula above.
Our milliliters per hour to cubic feet per second calculator automatically converts your flow rate measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
mL/h and cfs 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 Second?
A cubic feet per second is a unit of flow rate equal to 1,699.0107955 liters per minute (L/min), the base unit for flow rate. River hydrology flow unit equal to 28.3168 L/s. [2]
The cubic feet per second is classified as a US customary unit of flow rate. cfs can be abbreviated as ft³/s; for example, 1 cubic feet per second can be written as 1 ft³/s.
When working with cfs (ft³/s) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, cfs (ft³/s) are widely used across large-scale industrial, bulk, and macro-level flow rate specifications within US customary workflows, engineering documentation, and technical data sheets.
When converting flow rate between ml/h (mL/h) and cfs (ft³/s), keep full floating-point precision (1 mL/h = 9.80963e-9 ft³/s; 1 ft³/s = 101,940,647.7312 mL/h) during intermediate calculations and round only the final cubic feet per second figure to match your instrument tolerance.
