How it works

Enter a volume and choose its unit. One oil barrel is 42 US gallons, which is exactly 0.158 987 294 928 m³; Mbbl and MMbbl are thousand and million barrels.

Formula

1 bbl = 42 US gal = 0.158987 m³ = 158.987 L

Assumptions and limits

Volumes are converted at the same temperature. Crude oil expands and contracts with temperature, so custody-transfer volumes also need a correction to standard conditions (for example 15 °C or 60 °F), which this converter does not apply.

For education and quick estimates only. Check the result against the applicable standards and your project data before using it in design, operation or safety decisions.
