What Is This Tool?
This converter transforms volumetric flow rates measured in gallons (US) per day into mass flow rates expressed in kilograms per day for gasoline at a standard temperature of 15.5°C. It helps standardize gasoline flow measurements for applications like custody transfer and inventory management.
How to Use This Tool?
-
Enter the flow rate value in gallon (US)/day unit
-
Select gallon (US)/day as the source unit and kilogram/day (Gasoline at 15.5°C) as the target unit
-
Click the convert button to obtain the equivalent flow rate in kilograms per day
-
Use the result for custody transfer, inventory, or process flow calculations
Key Features
-
Converts gallon (US)/day to kilogram/day with reference to gasoline density at 15.5°C
-
Uses a precise fixed conversion rate for accurate mass flow calculation
-
Supports applications in petroleum refining, fuel transportation, and inventory control
-
Browser-based and easy to use without requiring specialized software
Examples
-
5 gallon (US)/day equals 13.9933 kilogram/day (Gasoline at 15.5°C)
-
10 gallon (US)/day equals 27.9866 kilogram/day (Gasoline at 15.5°C)
Common Use Cases
-
Reporting household or per-capita daily water consumption in the US (for gallon (US)/day context)
-
Custody transfer and invoicing for gasoline deliveries by pipeline or tanker
-
Inventory reconciliation and throughput monitoring at fuel depots and refineries
-
Calculating fuel consumption and emissions with temperature-corrected mass flow values
-
Describing small-scale pumping test flows or chemical dosing in water-treatment
Tips & Best Practices
-
Ensure gasoline flow measurements are referenced to 15.5°C for correct mass conversion
-
Use this tool only for gasoline flows to ensure relevant density assumptions
-
Cross-check results when temperature or gasoline composition may vary
-
Use consistent units and reference temperatures when comparing or reporting fuel flows
-
Apply the converter in petroleum-related industries for process control and billing
Limitations
-
This conversion assumes gasoline density at exactly 15.5°C; changes in temperature affect accuracy
-
Not suitable for fluids other than gasoline without adjusting for their specific densities
-
Accurate volumetric to mass conversions require stable temperature and density conditions
Frequently Asked Questions
-
What does converting from gallon (US)/day to kilogram/day (Gasoline at 15.5°C) mean?
-
It means transforming a volumetric flow measurement into a mass flow quantity standardized to a specific temperature to enable accurate custody and inventory calculations for gasoline.
-
Why is 15.5°C used as the reference temperature for gasoline?
-
15.5°C is a standard temperature in petroleum measurement that helps correct volumetric data to a consistent basis for mass flow comparisons and custody transfer.
-
Can I use this converter for fluids other than gasoline?
-
This tool is designed specifically for gasoline flow conversions with density referenced at 15.5°C and may not be accurate for other fluids without proper density adjustments.
Key Terminology
-
Gallon (US)/day [gal (US)/d]
-
A volumetric flow unit representing one US liquid gallon passing a point every day.
-
Kilogram/day (Gasoline at 15.5°C)
-
A mass flow rate expressing the kilograms of gasoline flowing per day, density-corrected to a standard temperature of 15.5°C.
-
Custody transfer
-
The process of transferring fuel ownership while accounting for precise quantities, often requiring temperature and mass corrections.
