What is a barrel (US)/day?

It is a volumetric flow rate measuring the number of US oil barrels passing a point in one day, where one barrel equals 42 US gallons or about 158.9873 liters.

When should I use milliliter/day as a flow unit?

Milliliter per day is suitable for representing very low continuous or cumulative flow rates such as clinical fluid output or small laboratory seepage rates.

Why convert barrel (US)/day to milliliter/day?

Converting allows expressing large oil production volumes in much smaller units useful for laboratory, clinical, or environmental measurements where detailed low-rate flow data is needed.

Enter the value you want to convert in barrel (US)/day
Select barrel (US)/day as the input unit and milliliter/day as the output unit
Click convert to see the equivalent flow rate in milliliters per day
Use the results to assist in measurement, comparison, or scaling in your application

Key Features

Converts volumetric flow rates from barrel (US)/day to milliliter/day
Displays conversions using standardized and recognized units
Facilitates adapting flow measurements across different scales
Supports applications in petroleum production, clinical monitoring, and laboratory studies

Examples

1 bbl (US)/day equals 158,987.295 mL/day
0.5 bbl (US)/day equals 79,493.647 mL/day

Common Use Cases

Reporting crude oil production rates for wells, fields, and countries
Measuring pipeline, tanker, or terminal throughput in oil logistics
Monitoring daily fluid output in medical and clinical settings
Assessing small flow rates in laboratory or environmental monitoring

Tips & Best Practices

Be aware of the large difference in scale when converting between units
Use careful unit management to avoid errors with large numbers
Choose units appropriate to your measurement scale and context
Cross-verify conversions when working across diverse industries

Limitations

Conversions may result in very large numbers due to scale differences
Barrels per day are usually not practical for very low flow measurements
Milliliters per day may not suit industrial-scale fluid flows
Context matters: each unit is best suited for specific application ranges
