Note:
The oil barrel is used as a unit of volume or capacity for crude oil and other petroleum products. In the United States, the oil production is expressed in oil barrels of 42 US liquid gallons. Elsewhere, the oil production is expressed in cubic meters (m³) or tonnes (t). The cubic meter is a unit of volume in the SI; the tonne is a unit of mass in the metric system. One tonne of oil ranges from 6 to 8 barrels of oil (bbl), depending on the oil density (mass = volume × density).
