What Is This Tool?
This converter transforms flow measurements from cubic foot per hour (ft³/h), a volume unit representing fluid flow rate through a point in one hour, into gallons (US) per hour (gal (US)/h), commonly used for liquid flow rates in various industrial and fuel consumption settings.
How to Use This Tool?
-
Enter the flow value in cubic foot per hour (ft³/h)
-
Select the input unit as cubic foot/hour and output unit as gallon (US)/hour
-
Click on convert to get the equivalent flow rate in US gallons per hour
-
Use the results to analyze or design systems involving volumetric flow
Key Features
-
Converts volumetric flow rate from cubic foot/hour to US gallon/hour
-
Supports measurements used in HVAC, fuel consumption, and dosing systems
-
Browser-based and easy to use for quick calculations
-
Helps translate gas or liquid flow values into familiar liquid volume units
Examples
-
2 ft³/h converts to 14.961038961 gal (US)/h
-
0.5 ft³/h converts to 3.74025974025 gal (US)/h
Common Use Cases
-
Specifying ventilation or exhaust rates in HVAC systems and ducts
-
Monitoring fuel burn rates in small aircraft and portable generators
-
Sizing pumps and blowers for low-to-moderate industrial flows
-
Chemical dosing and condensate removal in dosing systems
Tips & Best Practices
-
Ensure flow measurements are taken under standard conditions for accuracy
-
Be cautious when converting gas flows since density affects volume
-
Use this conversion to interpret gas or liquid flows in commonly understood units
-
Apply this tool for flow rates where US gallon units are the standard measurement
Limitations
-
Conversion mainly assumes standard temperature and pressure conditions
-
Does not account for changes in gas density or compressibility factors
-
Cubic foot/hour can apply to gas or liquid flow while gallon/hour is usually liquid flow
-
Verify suitability when interpreting gas flow rates in liquid-based units
Frequently Asked Questions
-
What does cubic foot/hour measure?
-
Cubic foot per hour (ft³/h) indicates the volume of fluid passing through a point every hour and applies to both gas and liquid flows.
-
Why convert cubic foot/hour to gallon (US)/hour?
-
Converting helps express flow rates in units more common in fuel consumption, liquid dosing, and other industrial applications using US gallons.
-
Are there any cautions when converting gas flows?
-
Yes, gas flows can vary with density and pressure, so standard conditions are assumed and variations should be considered separately.
Key Terminology
-
Cubic foot/hour (ft³/h)
-
A volumetric flow rate measuring the volume of one cubic foot of fluid passing through a point in one hour.
-
Gallon (US)/hour (gal (US)/h)
-
A flow rate unit describing the number of US liquid gallons passing a point each hour, commonly used in liquid volume measurements.
