Let's clarify the process of converting between Millilitres per second (mL/s) and Cubic inches per minute (in³/min). This conversion is important in fields dealing with fluid dynamics and flow rates, such as engineering and manufacturing. Since we're dealing with volume and time, the base (decimal or binary) doesn't affect the conversion.
Conversion Fundamentals
Converting between mL/s and in³/min relies on understanding the relationships between these units of volume and time.
- Volume: 1 milliliter (mL) is equal to 0.0610237 cubic inches (in³).
- Time: 1 second (s) is equal to 1/60 minutes.
Using these relationships, we can set up the conversion factors to move between the two units.
Converting 1 mL/s to Cubic Inches Per Minute
To convert 1 mL/s to in³/min, we use the following conversion:
Performing the calculation:
Therefore, 1 mL/s is approximately equal to 3.661422 in³/min.
Converting 1 in³/min to Millilitres Per Second
To convert 1 in³/min to mL/s, we use the inverse conversion factors:
Performing the calculation:
Therefore, 1 in³/min is approximately equal to 0.273319 mL/s.
Real-World Examples
These conversions are crucial in various fields:
- Automotive Engineering: Converting fuel injector flow rates is essential for engine performance and efficiency.
- Medical Devices: Infusion pumps require precise flow rates, often converted between mL/s and other units for accurate drug delivery.
- HVAC Systems: Calculating airflow and fluid flow rates in ventilation and cooling systems involves these unit conversions.
For example, a small fuel injector might have a flow rate of 200 mL/s. Converting this to cubic inches per minute provides engineers with a more intuitive understanding of the fuel being injected into the engine. Similarly, in medical settings, a doctor might prescribe an IV drip at a rate of 5 mL/s, which needs to be converted to in³/min for the equipment settings.

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 Inches per Minute?
Cubic inches per minute (in$^3$/min or CFM) is a unit of measure for volume flow rate. It represents the volume of a substance (typically a gas or liquid) that flows through a given area per minute, with the volume measured in cubic inches. It's a common unit in engineering and manufacturing, especially in the United States.
Understanding Cubic Inches and Volume Flow Rate
Cubic Inches
A cubic inch is a unit of volume equal to the volume of a cube with sides one inch long. It's part of the imperial system of measurement.
Volume Flow Rate
Volume flow rate, generally denoted as , is the volume of fluid which passes per unit time. The SI unit for volume flow rate is cubic meters per second ().
Formation of Cubic Inches per Minute
Cubic inches per minute is formed by combining a unit of volume (cubic inches) with a unit of time (minutes). This describes how many cubic inches of a substance pass a specific point or through a specific area in one minute.
Where:
- = Volume flow rate (in$^3$/min)
- = Volume (in$^3$)
- = Time (min)
Applications and Examples
Cubic inches per minute is used across various industries. Here are some real-world examples:
- Automotive: Measuring the air intake of an engine or the flow rate of fuel injectors. For instance, a fuel injector might have a flow rate of 100 in$^3$/min.
- HVAC (Heating, Ventilation, and Air Conditioning): Specifying the airflow capacity of fans and blowers. A small bathroom fan might move air at a rate of 50 in$^3$/min.
- Pneumatics: Determining the flow rate of compressed air in pneumatic systems. An air compressor might deliver 500 in$^3$/min of air.
- Manufacturing: Measuring the flow of liquids in industrial processes, such as coolant flow in machining operations. A coolant pump might have a flow rate of 200 in$^3$/min.
- 3D Printing: When using liquid resins.
Conversions and Related Units
It's important to understand how cubic inches per minute relates to other units of flow rate:
- Cubic Feet per Minute (CFM): 1 CFM = 1728 in$^3$/min
- Liters per Minute (LPM): 1 in$^3$/min ≈ 0.01639 LPM
- Gallons per Minute (GPM): 1 GPM ≈ 231 in$^3$/min
Interesting Facts
While there's no specific law directly associated with cubic inches per minute itself, the underlying principles of fluid dynamics that govern volume flow rate are described by fundamental laws such as the Navier-Stokes equations. These equations, developed in the 19th century, describe the motion of viscous fluids and are essential for understanding fluid flow in a wide range of applications. For more information you can read about it in the following Navier-Stokes Equations page from NASA.
