What Is This Tool?
This online converter transforms flow measurements from liter per day (L/d), a volumetric unit used for daily fluid volumes, into pound per hour (lb/h) representing mass flow of gasoline at a standardized temperature of 15.5°C. It aids in translating volumes into mass-based flow rates essential for fuel handling and engineering purposes.
How to Use This Tool?
-
Enter the gasoline flow value in liters per day (L/d) into the input field.
-
Select the output unit as pound per hour (Gasoline at 15.5°C).
-
Click the convert button to get the equivalent mass flow rate.
-
Review the result expressed in pounds per hour referenced to 15.5°C.
-
Use the converted value for engineering or operational calculations.
Key Features
-

Examples
-
Convert 10 L/d to lb/h: 10 × 0.0679142318 = 0.679142318 lb/h (Gasoline at 15.5°C).
-
Convert 50 L/d to lb/h: 50 × 0.0679142318 = 3.39571159 lb/h (Gasoline at 15.5°C).
Common Use Cases
-
Reporting daily gasoline volumes as an hourly mass flow rate for custody transfer.
-
Fuel consumption rate determination for engines and industrial burners.
-
Calibration and verification of flow meters measuring gasoline at standard temperature.
-
Environmental and performance monitoring requiring precise mass-based flow inputs.
Tips & Best Practices
-
Ensure gasoline temperature is close to 15.5°C for accurate conversion results.
-
Use consistent time units and understand the difference between daily volume and hourly mass.
-
Verify flow meter calibration aligns with temperature-referenced density conditions.
-
Avoid applying this conversion to fluids other than gasoline without proper adjustments.
-
Cross-check conversion results for critical custody-transfer calculations.
Limitations
-
Assumes gasoline density is referenced at 15.5 °C; temperature and composition deviations impact accuracy.
-
Volumetric input is daily flow while output is mass flow per hour — careful unit management needed.
-
Conversion is not valid for fluids other than gasoline without modifying for density and temperature differences.
Frequently Asked Questions
-
Why is temperature 15.5°C important in this conversion?
-
15.5°C is the standard reference temperature used for gasoline density to ensure consistent and accurate mass flow measurements in custody and engineering applications.
-
Can this converter be used for fluids other than gasoline?
-
No, the conversion is tailored specifically for gasoline at 15.5°C and does not apply accurately to other fluids without adjustments for density and temperature.
-
How does the difference in time units affect the conversion?
-
The input is a volumetric flow per day, while the output is a mass flow per hour, so understanding this difference is essential to interpret and use the converted results correctly.
Key Terminology
-
Liter per day (L/d)
-
A volumetric flow rate unit expressing how many liters of fluid pass per day, commonly used for measuring daily fluid volumes.
-
Pound per hour (Gasoline at 15.5°C)
-
A mass flow rate unit indicating pounds of gasoline passing a point each hour, referenced to a standard temperature of 15.5°C for density correction.
-
Custody Transfer
-
The process of transferring fuel ownership where accurate measurement of gasoline mass flow is critical.
