What Is This Tool?
This tool allows you to convert flow measurements from pound/day (Gasoline at 15.5°C), a mass flow rate referencing gasoline mass standardized at 15.5°C, into liter/second [L/s], a volumetric flow rate expressing volume passing per second. It is especially useful in petroleum industry contexts and engineering measurements.
How to Use This Tool?
-
Enter the flow value in pound/day (Gasoline at 15.5°C) that you want to convert.
-
Select the desired output unit as liter/second [L/s].

-
Calculating refinery throughput and mass balancing in gasoline processing and blending.
-
Fuel consumption or emissions reporting requiring mass flow data normalized to a reference temperature.
-
Laboratory and process flow measurements integrating mass and volumetric flow rates.
-
Engineering design and control involving fluid flow rate specifications.
Tips & Best Practices
-
Ensure gasoline temperature is standardized at 15.5°C for accurate mass to volume conversions.
-
Use precise density information when converting between mass and volumetric flow units.
-
Handle small volumetric flow values carefully in instrumentation and calculations due to typical low magnitude.
-
Utilize this conversion in petroleum industry and process engineering contexts where standardized mass flows must align with volumetric monitoring.
Limitations
-
Conversion assumes gasoline density at exactly 15.5°C; temperature deviations affect accuracy.
-
Variations in gasoline composition can lead to conversion errors.
-
The conversion output in liter/second often results in very small values requiring precise numerical handling.
-
Accurate density data is critical for exact mass to volume flow rate translations.
Frequently Asked Questions
-
Why is gasoline referenced at 15.5°C for this conversion?
-
Gasoline quantities are standardized to 15.5°C in the petroleum industry to maintain consistent density and enable reliable custody transfer and accounting.
-
Can this tool convert any gasoline mass flow rate to volumetric flow?
-
Yes, as long as the gasoline flow rate is expressed in pounds per day at the standard 15.5°C temperature reference.
-
Why are liter/second flow rates so small compared to pound/day values?
-
Because pound/day measures mass over a day, converting to volumetric flow per second yields smaller numerical values reflecting the unit differences in time and measurement type.
Key Terminology
-
pound/day (Gasoline at 15.5°C)
-

-
liter/second [L/s]
-
A unit of volumetric flow rate indicating how many liters of fluid pass through a point each second.
-
Custody Transfer
-
The process of transferring petroleum product ownership and responsibility between parties, requiring standardized flow measurements.
