What is millilitres per second?
Millilitres per second (mL/s) is a unit of volumetric flow rate, describing the volume of fluid that passes through a given point per unit of time. It's commonly used in various fields where precise measurement of small fluid volumes is essential.
Definition of Millilitres per Second
Millilitres per second (mL/s) is a derived unit. It combines the metric unit of volume, the milliliter (mL), with the SI unit of time, the second (s). One milliliter is equal to one cubic centimeter (). Therefore, 1 mL/s is equivalent to 1 cubic centimeter of fluid flowing past a point in one second.
How Millilitres per Second is Formed
The unit is formed by expressing volume in milliliters and dividing it by time in seconds.
Common Applications and Examples
- Medical Applications: Infusion pumps deliver medication at precise rates, often measured in mL/s. For instance, a doctor might prescribe an IV drip at a rate of 0.5 mL/s.
- Laboratory Experiments: Chemical reactions and experiments often require precise control over the flow of liquids. Microfluidic devices frequently operate in the mL/s range or even lower.
- Small Engine Fuel Consumption: The fuel consumption of a small engine, like a lawnmower, can be expressed in mL/s. For example, an engine might consume 2 mL/s of gasoline at idle.
- 3D Printing: In material extrusion 3D printing, the flow rate of the melted filament is often controlled and can be expressed in mL/s.
- Water flow from faucets: A slowly dripping faucet might release water at a rate of approximately 0.1 mL/s. A fully open faucet might release water at a rate of 200 mL/s.
Relationship to Other Units
Millilitres per second can be converted to other volumetric flow rate units:
- Liters per second (L/s): 1 L/s = 1000 mL/s
- Cubic meters per second (): 1 = 1,000,000 mL/s
- Gallons per minute (GPM): 1 GPM ≈ 0.0630902 L/s ≈ 63.0902 mL/s
Notable Figures and Laws
While no specific law is directly associated with milliliters per second, the concept of flow rate is fundamental in fluid dynamics. Key figures in this field include:
- Daniel Bernoulli: Known for Bernoulli's principle, which relates fluid speed to pressure.
- Osborne Reynolds: Known for the Reynolds number, which helps predict flow patterns in fluids.

What is Cubic Feet per Second?
Cubic feet per second (CFS) is a unit of measurement that expresses the volume of a substance (typically fluid) flowing per unit of time. Specifically, one CFS is equivalent to a volume of one cubic foot passing a point in one second. It's a rate, not a total volume.
Formation of Cubic Feet per Second
CFS is derived from the fundamental units of volume (cubic feet, ) and time (seconds, ). The volume is usually calculated based on area and velocity of the fluid flow. It essentially quantifies how quickly a volume is moving.
Key Concepts and Formulas
The volume flow rate () can be calculated using the following formula:
Where:
- is the volume flow rate (CFS)
- is the cross-sectional area of the flow ()
- is the average velocity of the flow ()
Alternatively, if you know the volume () that passes a point over a certain time ():
Where:
- is the volume flow rate (CFS)
- is the volume ()
- is the time (seconds)
Notable Associations
While there isn't a specific "law" named after someone directly tied to CFS, the principles behind its use are rooted in fluid dynamics, a field heavily influenced by:
- Isaac Newton: His work on fluid resistance and viscosity laid the foundation for understanding fluid flow.
- Daniel Bernoulli: Known for Bernoulli's principle, which relates fluid pressure to velocity and elevation. This principle is crucial in analyzing flow rates.
For a more in-depth understanding of the relationship between pressure and velocity, refer to Bernoulli's Principle from NASA.
Real-World Examples
-
River Flows: The flow rate of rivers and streams is often measured in CFS. For example, a small stream might have a flow of 5 CFS during normal conditions, while a large river during a flood could reach thousands of CFS. The USGS WaterWatch website provides real-time streamflow data across the United States, often reported in CFS.
-
Water Supply: Municipal water systems need to deliver water at a specific rate to meet demand. The flow rate in water pipes is calculated and monitored in CFS or related units (like gallons per minute, which can be converted to CFS) to ensure adequate supply.
-
Industrial Processes: Many industrial processes rely on controlling the flow rate of liquids and gases. For example, a chemical plant might need to pump reactants into a reactor at a precise flow rate measured in CFS.
-
HVAC Systems: Airflow in heating, ventilation, and air conditioning (HVAC) systems is sometimes specified in cubic feet per minute (CFM), which can be easily converted to CFS by dividing by 60 (since there are 60 seconds in a minute). This helps ensure proper ventilation and temperature control.

When would I use a Millilitres per second to Cubic feet per second conversion?
This conversion is useful when comparing small liquid flow measurements with larger engineering or industrial flow systems. For example, laboratory equipment may measure flow in ml/s, while fluid transport or ventilation calculations may use ft$^3$/s. Converting between them helps keep units consistent across different applications.
Why is the converted value from ml/s to ft$^3$/s so small?
A millilitre is a very small unit of volume, so its equivalent in Cubic feet is also very small. Since , the result will usually be a small decimal unless the ml/s value is large.
