What volume does one barrel (US) represent?

One US oil barrel equals 42 US gallons or about 158.987 liters, commonly used in the petroleum industry.

Why convert barrel (US) volumes to cubic kilometers?

This conversion helps understand enormous petroleum volumes in terms of geological or hydrological contexts like reservoirs or ice sheets.

Can I use this tool for small volume conversions?

Due to the scale difference and small conversion factor, it's better suited for large aggregate volumes rather than small quantities.

What Is This Tool?

This converter allows you to change volume units from barrel (US), commonly used in the petroleum industry, into cubic kilometers, a unit suitable for representing very large volumes, such as those in hydrology and geology.

How to Use This Tool?

Enter the volume value in barrel (US) units you want to convert.
Select barrel (US) as the starting unit and cubic kilometer as the target unit.
Click the convert button to get the equivalent volume in cubic kilometers.

Key Features

Converts from barrel (US) to cubic kilometers accurately based on defined volume equivalences.
Browser-based and easy to use for quick volume conversions relevant to energy and environmental sectors.
Supports understanding of large petroleum resource volumes in relation to natural and engineered water bodies.

Examples

Convert 10 barrels (US) to cubic kilometers to get 1.19240471196e-9 km³.
Convert 1,000,000 barrels (US) to cubic kilometers resulting in 0.000119240471196 km³.

Common Use Cases

Reporting crude oil production and trade metrics such as barrels per day.
Quantifying petroleum storage and shipment volumes for inventory and logistics planning.
Comparing petroleum volumes to geological or hydrological scales in environmental and resource management studies.

Tips & Best Practices

Use the conversion for aggregate data rather than individual small volumes due to the large scale difference.
Be aware of precision requirements to avoid rounding errors in very large volume calculations.
Compare petroleum volumes to large natural or engineered water bodies to contextualize resource sizes.

Limitations

The very small conversion factor makes cubic kilometers impractical for everyday petroleum volume measurements.
Conversions are better suited for large-scale volumes rather than small quantities due to scale differences and rounding sensitivity.
