What Is This Tool?
This converter translates volumetric flow rates in US gallons per hour to mass flow rates in kilograms per day standardized to gasoline at 15.5°C. It’s designed for applications needing temperature-corrected fuel mass flow measurements.
How to Use This Tool?
-
Enter the flow rate value in gallon (US)/hour.
-
Select the source unit as gallon (US)/hour and the target unit as kilogram/day (Gasoline at 15.5°C).
-
Click the convert button to obtain the equivalent mass flow rate.
-
Use the result for fuel accounting, reporting, or process calculations.
Key Features
-
Converts US gallon per hour volumetric flow to mass flow in kilogram per day for gasoline.
-
Applies to gasoline density referenced at 15.5°C for standardized measurements.
-
Supports petroleum industry uses such as custody transfer and inventory management.
-
Online, easy-to-use interface suitable for refinery and fuel depot operations.
Examples
-
2 gal (US)/h converts to approximately 134.34 kg/day for gasoline at 15.5°C.
-
0.5 gal (US)/h converts to about 33.58 kg/day under the same conditions.
Common Use Cases
-
Fuel consumption measurement for small aircraft and marine engines reporting in gal/h.
-
Custody transfer invoicing for gasoline deliveries by pipeline or tanker using mass basis at 15.5°C.
-
Inventory reconciliation and throughput in fuel depots and refineries ensuring temperature-corrected flow data.
-
Calculating emissions or process mass balances in refining and distribution systems.
Tips & Best Practices
-
Always ensure the gasoline temperature standard is 15.5°C when using this conversion.
-
Use this tool for gasoline only; different fuels require their own conversion factors.
-
Double-check volumetric measurements and densities when precise accounting is critical.
-
Apply conversion results for custody transfer documentation and operational analysis.
Limitations
-
Conversion assumes gasoline density at a fixed reference temperature of 15.5°C.
-
Accuracy may vary with temperature or changes in gasoline composition.
-
Different fuels or temperature standards use other conversion factors.
-
Volumetric-to-mass conversions depend on accurate density values that may vary by blend.
Frequently Asked Questions
-
Why is the temperature 15.5°C important for this conversion?
-
The temperature of 15.5°C is a reference standard used for gasoline to correct volumetric measurements to a common basis for consistent mass–volume conversion and custody transfer.
-
Can this conversion be used for fuels other than gasoline?
-
No, this specific conversion factor applies to gasoline at 15.5°C. Different fuels require different conversion rates due to varying densities and temperature standards.
-
What is the practical use of converting from gal (US)/h to kg/day for gasoline?
-
Converting from volumetric to mass flow helps in precise accounting, reporting, custody transfer, and inventory management in petroleum operations ensuring consistency regardless of temperature.
