Understanding US Oil Barrels to Board Feet Conversion
The US oil barrel (bbl) is the petroleum volume unit equal to 42 US gallons, about 158.987 litres. The board foot is a volume unit used in North American lumber, equal to a piece one foot square and one inch thick—about 2,360 cubic centimetres. Although they come from very different trades, both are volumes, so this conversion offers a concrete way to visualize how much space a barrel of oil occupies in familiar timber terms.

How to Convert US Oil Barrels to Board Feet
Translate a petroleum volume into lumber board feet with one multiplication.
- Identify the value: Note the volume in US oil barrels (bbl).
- Apply the factor: Multiply by 67.375, the number of board feet in one barrel.
- Interpret the result: Treat the answer as the equivalent volume of one-inch-thick, one-foot-square boards.
- Worked result: For 25 bbl, board feet.

What is the US Oil Barrel?
The US oil barrel (bbl) is a unit of volume equal to 42 US gallons, used almost exclusively for crude oil and petroleum products. It is the standard trading unit of the global oil industry.
Definition
The US oil barrel is defined as exactly 42 US liquid gallons:
Precisely, 1 bbl = 158.987294928 liters. This differs from other "barrel" definitions: the US fluid barrel is 31.5 gallons, the US federal beer barrel is 31 gallons, and the UK barrel is about 163.66 liters.
Origin and History
The 42-gallon standard traces to the early Pennsylvania oil boom of the 1860s. Producers adopted the 42-gallon "tierce" wooden barrel, which was slightly larger than the common 40-gallon whiskey barrel, allowing for spillage and evaporation losses during transport. In 1872 the Petroleum Producers Association formalized 42 gallons as the standard, and it endures today even though oil is now moved by pipeline and tanker rather than in physical barrels.
Law and Notable Facts
The oil barrel is not an SI unit but is deeply embedded in commodity markets, where crude prices are quoted per barrel and production in barrels per day (bbl/d). The abbreviation "bbl" is thought to stand for "blue barrels" once used by Standard Oil. Physical 42-gallon barrels are rarely used in the modern industry.
Real-World Examples and Conversions
- 1 bbl = 42 US gallons ≈ 34.97 imperial gallons ≈ 158.99 liters.
- Global crude oil consumption is roughly 100 million barrels per day.
- A single barrel of crude yields about 19 to 20 US gallons of gasoline after refining.
- 1 metric ton of crude oil is roughly 7.33 barrels, depending on density.
What is the Board Foot?
The board foot is a unit of volume used in North America to measure sawn lumber and hardwood. It represents a piece of wood one foot long, one foot wide, and one inch thick.
Definition
A board foot is defined as exactly 144 cubic inches — the volume of a board 12 in × 12 in × 1 in.
Equivalently, one board foot equals cubic foot, or 2,359.74 cubic centimetres.
Origin and History
The board foot arose in the 19th-century American and Canadian lumber trade as a practical way to price rough-sawn timber by wood content rather than by finished dimensions. Because a "1-inch" board and a "12-inch" width refer to nominal (pre-planing) sizes, the board foot standardized how mills, wholesalers, and builders quoted and sold lumber. It remains the customary trade unit in the United States and Canada today.
Law and Notable Facts
The board foot is recognized in U.S. and Canadian lumber commerce and standards, where large volumes are quoted in "thousand board feet" (MBF), with M denoting the Roman numeral for 1,000. Board-foot content is calculated from nominal dimensions, so a nominal "2×4" (actually about 1.5 in × 3.5 in when surfaced) is still counted at its nominal 2 in × 4 in size — meaning the buyer pays for wood removed during planing. Rough-sawn hardwoods are commonly measured in "quarters" of nominal thickness (4/4, 5/4, 8/4).
Real-World Examples and Conversions
- A board 8 ft long × 6 in wide × 1 in thick contains board feet.
- A nominal 2×4 stud 8 ft long counts as board feet.
- One thousand board feet (1 MBF) equals about 2.36 cubic metres of wood, a typical way to price bulk lumber shipments.
- One board foot equals roughly 2.36 litres, so a small stack of ten board feet holds about 23.6 litres of wood volume.
