Understanding US Bushels to Board Feet Conversion
A board foot is a unit of lumber volume equal to 144 cubic inches (a 1 ft by 1 ft board, 1 inch thick), roughly 2.36 litres. It is the timber industry's standard measure for pricing and estimating sawn wood. Expressing a bushel in board feet is a practical cross-check for anyone estimating how much sawn timber occupies the same space as a bushel of dry produce, useful in mixed farm-and-mill inventory work.

How to Convert US Bushels to Board Feet
Use the fixed volume factor between the US dry bushel and the Board Foot to convert in a single multiplication.
- Start with your bushel value: note the quantity in US Bushels that you want to convert.
- Apply the factor: multiply that quantity by 14.9335, the number of board-foot in one bu.
- Read the result: the product is your volume in Board Feet; to reverse, divide by the same factor.
- Worked result: 25 US Bushels become board-foot.

What is the US Bushel?
The US bushel is a large United States customary unit of dry volume used chiefly in agriculture to measure grain, fruit, and other bulk crops. It is the foundation of the US dry-measure system.
Definition
The US bushel (the Winchester bushel) is defined as exactly 2150.42 cubic inches.
This equals 2150.42 × 16.387064 cm³ = 35239.07 cm³. One bushel contains 4 pecks, 32 dry quarts, or 64 dry pints. It should not be confused with the imperial bushel (36.36872 L), which is about 3% larger.
Origin and History
The Winchester bushel dates to a 1696 English statute (with roots in medieval standards kept at Winchester) and was defined as a cylinder 18.5 inches in diameter and 8 inches deep, giving 2150.42 in³. The United States adopted this measure, while Great Britain replaced it with the imperial bushel in 1824.
Law and Notable Facts
Although volumetric by definition, US grain trading uses the bushel as a weight-based unit: legal "bushel weights" fix a bushel of wheat or soybeans at 60 pounds, corn and rye at 56 pounds, and oats at 32 pounds. Commodity exchanges quote grain prices per bushel on this weight basis.
Real-World Examples and Conversions
- A bushel of shelled corn weighs 56 lb (about 25.4 kg) and occupies roughly 35.24 liters of loose volume.
- 1 US bushel = 4 pecks = 8 US dry gallons = 35.2391 L.
- 1 US bushel ≈ 0.9689 imperial bushel; 1 cubic meter ≈ 28.38 US bushels.
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.
