Converting between volume flow rates like milliliters per second (mL/s) and cubic inches per hour (in³/hr) is a common task in various fields, from engineering to everyday life. The conversion hinges on understanding the relationships between metric and imperial units. This section will detail the steps to convert between these units, highlight real-world examples, and touch on related principles.
Understanding the Conversion Factors
To convert between milliliters per second and cubic inches per hour, you need to know the conversion factors:
- 1 milliliter (mL) is equal to 0.0610237 cubic inches (in³).
- 1 hour is equal to 3600 seconds.
Given these, we can derive the primary conversion factor:
Converting Millilitres per Second to Cubic Inches per Hour
To convert from mL/s to in³/hr, multiply the value in mL/s by the conversion factor 219.685.
Example: Convert 1 mL/s to in³/hr.
Therefore, 1 mL/s is approximately equal to 219.685 cubic inches per hour.
Converting Cubic Inches per Hour to Millilitres per Second
To convert from in³/hr to mL/s, divide the value in in³/hr by the conversion factor 219.685, or equivalently, multiply by its reciprocal, which is approximately 0.004552.

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 hour?
Cubic inches per hour is a unit of volume flow rate. The following sections describe cubic inches per hour in more detail.
Understanding Cubic Inches per Hour
Cubic inches per hour (in$^3$/hr) is a unit used to measure the volume of a substance (liquid or gas) that flows past a certain point in a specific amount of time. It indicates how many cubic inches of a substance move within one hour.
Formation of Cubic Inches per Hour
This unit is derived from two base units:
- Cubic inch (in$^3$): A unit of volume. It represents the volume of a cube with sides of 1 inch each.
- Hour (hr): A unit of time.
The unit is formed by dividing a volume expressed in cubic inches by a time expressed in hours, resulting in a rate of flow:
Applications of Cubic Inches per Hour
Cubic inches per hour is practically used in real-world applications where the measurement of slow, very small volume flow rate is important. The SI unit for Volume flow rate is . Some examples are:
- Small Engine Fuel Consumption: Measuring the fuel consumption of small engines, such as those in lawnmowers or model airplanes.
- Medical Devices: Infusion pumps may use this unit to measure how slowly medicine flows into the patient.
- Hydraulics: Very small scale of hydraulic flow, where precision is needed.
- 3D Printing: Material extrusion volume in 3D printing, particularly for small-scale or intricate designs.
Conversion to Other Units
Cubic inches per hour can be converted to other units of volume flow rate, such as:
- Cubic feet per hour (ft$^3$/hr)
- Gallons per hour (gal/hr)
- Liters per hour (L/hr)
- Cubic meters per second (m$^3$/s)
Flow Rate
Flow rate, generally speaking, plays an important role in many different areas of science and engineering. For example, cardiovascular system uses the concept of flow rate to determine blood flow.
