What Is This Tool?
This tool converts volumetric flow rates from cubic inch per hour, a unit representing very low volume flow in imperial units, to liter per second, a common SI flow rate unit used in engineering and laboratory contexts.
How to Use This Tool?

Tips & Best Practices
-
Ensure accurate input values for small flow rates to avoid errors
-
Use this tool for converting low volumetric flows from imperial to SI units
-
Apply conversions carefully in calibration and design to maintain precision
-
Consider instrumental precision when measuring low flow rates
-
Verify conversion outputs before using in critical engineering calculations
Limitations
-
Converted values are very small and require careful handling to prevent rounding or measurement errors
-
Accurate calibration devices are essential to reliably measure the low flow rates in cubic inch/hour
-
Not suitable for high flow rates due to low magnitude of cubic inch/hour unit
Frequently Asked Questions
-
What does cubic inch per hour measure?
-
It measures volumetric flow rate as one cubic inch of volume passing a point every hour, mostly used for very low flow rates.
-
Why convert cubic inch/hour to liter/second?
-
Converting to liter/second standardizes flow measurements for engineering, laboratory, and industrial systems that use SI units.
-
Can I use this tool for high flow rates?
-
No, because cubic inch/hour represents very low flow rates, the tool is not suited for higher flow conversions.
Key Terminology
-
Cubic inch per hour [in^3/h]
-
A volumetric flow rate unit indicating one cubic inch of volume flowing through a cross-section every hour, used for very low flow measurement.
-
Liter per second [L/s]
-
A volumetric flow rate unit representing one liter of volume passing through a cross-section every second, commonly used in SI unit systems.
