What Is This Tool?
This tool converts volumetric flow rates from gallon (US)/minute, a liquid flow measurement, to hundred-cubic foot/hour, commonly used for gas or air flow rates. It assists users in expressing flow values between liquid and gas volumetric units.
How to Use This Tool?
-
Enter the flow rate value in gallon (US)/minute.
-
Select gallon (US)/minute as the source unit.
-
Choose hundred-cubic foot/hour as the target unit.
-
Click convert to get the equivalent flow rate.
Key Features
-
Converts between gallon (US)/minute and hundred-cubic foot/hour units.
-
Browser-based and simple to use without needing formulas.
-
Provides instant results for plumbing, HVAC, and gas flow applications.
Examples
-
5 gallon (US)/minute equals 0.401041667 hundred-cubic foot/hour.
-
10 gallon (US)/minute converts to 0.802083333 hundred-cubic foot/hour.
Common Use Cases
-
Determining pump or sprinkler system capacities in plumbing.
-
Evaluating HVAC water flow and cooling tower circulation rates.
-
Measuring fuel transfer rates in automotive or small-engine contexts.
-
Reporting residential natural gas consumption or small gas flow rates.
-
Sizing pilot lines, burners, or process gas supplies.
-
Converting ventilation and exhaust flow rates in imperial units.
Tips & Best Practices
-
Confirm that the flow relates to the correct fluid type (liquid vs. gas) before converting.
-
Use the conversion for volumetric comparisons, not for precise gas flow under variable pressure or temperature.
-
Verify unit selections match your measurement context in plumbing, HVAC, or gas metering.
Limitations
-
Conversion assumes volumetric equivalence without accounting for fluid density or compressibility.
-
Pressure and temperature effects on gas volume are not considered.
-
The units measure different fluid types, limiting direct physical equivalence.
Frequently Asked Questions
-
Can I use this conversion for gas flow rates directly?
-
This conversion translates volumetric flow rates but does not account for gas density or compressibility, so it is intended for volume comparisons rather than precise gas flow calculations.
-
Why are gallon (US)/minute and hundred-cubic foot/hour used in different contexts?
-
Gallon (US)/minute is typically used for liquid flows like water or fuel, while hundred-cubic foot/hour is common for low-to-moderate gas or air flows in utility and ventilation applications.
-
Does this tool consider pressure or temperature variations in flow rates?
-
No, the conversion is strictly volumetric and time-based and does not factor in pressure or temperature effects on gas volumes.
Key Terminology
-
gallon (US)/minute
-
A unit measuring the number of U.S. liquid gallons passing a point each minute, used mainly for liquid flow rates.
-
hundred-cubic foot/hour
-
A volumetric flow rate representing 100 cubic feet passing a point each hour, commonly used for gas or air flow measurement.
-
volumetric flow rate
-
The volume of fluid passing through a section per unit of time.
