What Is This Tool?
This unit converter transforms flow measurements from US gallons per hour, a volumetric rate, to pounds per hour of gasoline at 15.5°C, a mass flow rate corrected for temperature. It helps in applications where fuel volume needs to be expressed as mass with temperature adjustment.
How to Use This Tool?
-
Enter the flow value in gallon (US)/hour units
-
Select gallon (US)/hour as the input unit and pound/hour (Gasoline at 15.5°C) as the output
-
Click the convert button to get the equivalent mass flow in lb/h
-
Review the result which reflects fuel mass flow corrected to standard temperature
Key Features
-
Converts volumetric flow (gal (US)/h) to mass flow (lb/h) for gasoline at 15.5°C
-
Applies a standardized conversion factor ensuring consistent temperature correction
-
Supports fuel flow rate conversions critical for engineering and custody transfer
-
Useful for aviation, marine, generator fuel monitoring, and industrial fuel management
Examples
-
2 gal (US)/h converts to approximately 12.34 lb/h (Gasoline at 15.5°C)
-
0.5 gal (US)/h converts to approximately 3.085 lb/h (Gasoline at 15.5°C)
Common Use Cases
-
Converting aircraft and marine engine fuel burn rates reported in gal/h to mass flow rates
-
Specifying and verifying flow rates for small industrial pumps and dosing systems
-
Fuel custody transfer and metering in pipelines and terminals with temperature-corrected mass flow
-
Calibration and performance checks of fuel delivery systems requiring temperature-referenced measurements
Tips & Best Practices
-
Ensure the gasoline density reference temperature is maintained at 15.5°C for accuracy
-
Use consistent units and temperature references when comparing or using flow data
-
Apply this conversion only for gasoline or fuels with similar density properties
-
Verify conversions by cross-checking with measurement device specifications or calibration data
Limitations
-
Conversion assumes gasoline density at 15.5°C; temperature deviations may impact accuracy
-
Specific to gasoline and not directly applicable to other fuels without density and temperature adjustments
-
Measurement inaccuracies and changes in fuel composition can affect conversion precision
Frequently Asked Questions
-
Why is the temperature 15.5°C important in this conversion?
-
The temperature 15.5°C is used as a standard reference for gasoline density to ensure mass flow measurements are temperature-corrected for accuracy in custody and engineering calculations.
-
Can this conversion be used for fuels other than gasoline?
-
This specific conversion applies only to gasoline at 15.5°C. Other fuels require appropriate density and temperature corrections before conversion.
-
What is the conversion factor from gallon (US)/hour to pound/hour (Gasoline at 15.5°C)?
-
The conversion factor is approximately 6.17; 1 gal (US)/h equals 6.169999998 lb/h for gasoline at 15.5°C.
Key Terminology
-
Gallon (US)/hour [gal (US)/h]
-
A volumetric flow rate measuring the number of US liquid gallons flowing past a point per hour, commonly used in non-SI contexts.
-
Pound/hour (Gasoline at 15.5°C)
-
A mass flow rate unit indicating pounds of gasoline passing a point each hour, adjusted to a reference temperature for density correction.
-
Custody Transfer
-
The process of transferring fuel ownership where accurate measurement, including temperature and density correction, is critical.
