Understanding US Pecks to Board Feet Conversion
A US peck (pk) is a dry-capacity unit of about 8.810 litres, a quarter of a bushel used for produce, while a board foot (board-foot) is a lumber volume equal to a piece 12 inches square and 1 inch thick, roughly 2.360 litres or 1/12 of a cubic foot. Converting pecks to board feet lets you express a dry produce volume in the timber-industry unit used to price and tally sawn wood.
Conversion Formula
To convert US Pecks to Board Feet, multiply by this factor:
Step-by-Step Example

What is the US Peck?
The US peck is a United States customary unit of dry volume, equal to a quarter of a bushel, used for measuring fruit, vegetables, and grain. It sits between the dry gallon and the bushel in the dry-measure system.
Definition
The US peck is defined as one quarter of a US bushel, or 8 US dry quarts, equal to exactly 537.605 cubic inches.
With the bushel fixed at 2150.42 in³, a peck equals 2150.42 ÷ 4 = 537.605 in³ = 8809.77 cm³. The US peck is about 3% smaller than the imperial peck (9.09218 L).
Origin and History
The peck is an old English dry measure, attested since the 14th century and long used for grain and produce. Its US form is tied to the Winchester bushel retained from colonial England, while the imperial peck follows Britain's 1824 reform.
Law and Notable Facts
The peck endures in the tongue-twister "Peter Piper picked a peck of pickled peppers" and in US orchard sales, where apples are still sold by the peck and half-peck. It remains a legal customary unit defined via the international inch.
Real-World Examples and Conversions
- A peck of apples weighs roughly 10–12 lb and fills about 8.81 liters.
- 1 US peck = 8 US dry quarts = 16 US dry pints = 8.80977 L.
- 4 US pecks make 1 US bushel; 1 liter ≈ 0.11351 US peck.
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.
Frequently Asked Questions
How many board feet are in one US peck?
One US peck equals about 3.733368 board feet, comparing the peck's 8.810 litres to a board foot's 2.360 litres.
What is a board foot?
A board foot is a lumber-volume unit equal to a board 12 inches wide, 12 inches long, and 1 inch thick, or one-twelfth of a cubic foot.
How do I convert board feet back to US pecks?
Multiply the board-foot figure by 0.2678547, so 10 board feet equals about 2.679 pecks.
Is this a common practical conversion?
Not typically, since pecks measure produce and board feet measure sawn timber; the conversion is mainly for cross-referencing volumes between the two systems.
What is 6 US pecks in board feet?
Six pecks equal board feet.
