What Is This Tool?
This tool converts flow rates from gallon (US)/second, a unit for high-volume liquid flow, to cubic inch per hour [in^3/h], which measures very low flow volumes. It helps translate between large-scale fluid volumes and fine, precise flow rates.
How to Use This Tool?

Specifying high-capacity water or firefighting pump discharge rates
-
Measuring flow in irrigation systems, large plumbing valves, and industrial water lines
-
Estimating throughput in short liquid transfer operations like tanker unloading
-
Determining leak rates in sealed systems such as vacuum chambers and refrigerant leaks
-
Low-flow dosing in laboratory and microfluidic devices
-
Calibration of very-low-flow pumps and drip-feed equipment
Tips & Best Practices
-
Ensure you select the correct units to avoid conversion errors
-
Use cubic inch/hour for very low flow rates to maintain meaningful values
-
For large flow rates, be cautious of very large numbers after conversion
-
Consult examples to understand scaling between units
-
Consider the application context to choose the most appropriate flow units
Limitations
-
Large differences in magnitude can produce very large numbers requiring careful handling
-
Cubic inch/hour is designed for very low flow rates and may be impractical for high flows
-
Precision and rounding may need extra attention when converting between these units
Frequently Asked Questions
-
What does gallon (US)/second measure?
-
It measures volumetric flow rate, indicating how many US liquid gallons pass a point each second.
-
Why convert to cubic inch/hour?
-
Cubic inch/hour quantifies very low-volume flows, useful for leak detection and precise dosing where fine flow rates matter.
-
Is this converter suitable for all flow rate ranges?
-
It is ideal for converting high flow rates to very low flow units, but cubic inch/hour may not be practical for very large flow rates.
Key Terminology
-
Gallon (US)/second
-
A flow rate unit equal to one US liquid gallon passing a point each second.
-
Cubic inch/hour [in^3/h]
-
A volumetric flow unit representing one cubic inch of volume flowing per hour, used for very low flow rates.
-
Volumetric Flow Rate
-
The quantity of volume passing through a cross-section per unit time.
