What Is This Tool?
This converter transforms volumetric flow rates from liter per minute (L/min), a metric unit commonly used in engineering and medical fields, to cubic inch per hour (in³/h), an imperial unit specialized for very low-volume flows. It supports accurate conversion for applications requiring both metric and US customary units.
How to Use This Tool?
-
Enter the flow rate value in liters per minute (L/min)
-
Select liter/minute as the source unit and cubic inch/hour as the target unit

0.5 L/min converts to about 1830.71 cubic inch/hour
Common Use Cases
-
Adjusting respiratory therapy oxygen flow settings between metric and imperial units
-
Calibrating and selecting small pumps like aquarium or laboratory peristaltic pumps
-
Measuring leak rates in sealed systems such as vacuum chambers or refrigerant leaks
-

-
Specifying and verifying drip-feed device flow rates
Tips & Best Practices
-
Ensure accurate input values to maintain conversion reliability
-
Use cubic inch/hour units primarily for low volume flows to keep results intuitive
-
Double-check units especially when working across medical and engineering domains
-
Consider flow stability and measurement precision when interpreting converted values
Limitations
-
While the mathematical conversion is exact, practical measurements may vary due to flow fluctuations
-
Large flow rates converted to cubic inch/hour result in large numbers that might be harder to interpret
-
Cubic inch/hour is best suited for very low flow applications and may not be ideal for high-volume flows
Frequently Asked Questions
-
What does 1 liter per minute represent in flow measurement?
-
It represents the volume of fluid or gas passing a point each minute, commonly used to express moderate flows in metric units.
-
Where is the unit cubic inch per hour commonly applied?
-
It is used for specifying very low flow rates, such as leak detection, microfluidic dosing, and calibration of low-flow pumps.
-
Is this conversion tool suitable for all flow rate sizes?
-
It's most appropriate for moderate to low flows; very large flows converted to cubic inch/hour produce large numerical values that might be difficult to interpret.
Key Terminology
-
Liter/minute [L/min]
-
A metric volumetric flow rate measuring fluid volume passing a point per minute, used in medical and engineering fields.
-
Cubic inch/hour [in³/h]
-
An imperial unit of volumetric flow rate representing one cubic inch passing a cross-section every hour, suited for very low flow measurements.
-
Volumetric Flow Rate
-
The quantity of fluid passing through a section per unit of time, often expressed in units like L/min or in³/h.
