Understanding US Dry Quarts to Board Feet Conversion
The US dry quart (qt-dry) is a dry-volume unit of roughly 1101 cubic centimeters used for grains and produce. The board foot (board-foot) is a lumber-volume unit equal to a piece of wood 12 inches square and 1 inch thick, about 2360 cubic centimeters. Since a board foot is a bit larger than two dry quarts, converting quarts to board feet yields values a little under half the input.
Conversion Formula
To convert US Dry Quarts to Board Feet, multiply by this factor:
Step-by-Step Example
Convert 25 US Dry Quarts to Board Feet.
How to Convert US Dry Quarts to Board Feet
Translate a dry-quart volume into lumber board feet with a single factor.
- Record dry quarts: Note the volume in US dry quarts.
- Multiply by 0.466671: This gives board feet per dry quart.

What is the US Dry Quart?
The US dry quart is a unit of volume in the United States customary system used to measure dry commodities such as grains, berries, and produce. It is distinct from the (smaller) US liquid quart and belongs to the "dry measure" family built on the bushel.
Definition
The US dry quart is defined as one thirty-second of a US bushel, or equivalently 2 US dry pints, equal to exactly 67.200625 cubic inches.
Because the bushel is fixed at exactly 2150.42 cubic inches, the dry quart equals 2150.42 ÷ 32 = 67.200625 in³ = 1101.22094 cm³. It is about 16% larger than the US liquid quart (0.946353 L), so dry and liquid quarts must never be interchanged.
Origin and History
Dry measures descend from the English Winchester bushel, standardized in the 15th century and carried to colonial America. When the United Kingdom adopted the imperial system in 1824, the US retained the older Winchester standard, which is why US dry and imperial measures diverge to this day.
Law and Notable Facts
The US dry quart remains a legal customary unit, defined by the National Institute of Standards and Technology (NIST) via the international inch of 25.4 mm. In everyday US commerce, produce like berries is often sold in "dry pint" and "dry quart" containers, though these are nominal sizes rather than precisely enforced volumes.
Real-World Examples and Conversions
- A US dry quart of blueberries holds roughly 1.10 liters, or about 0.85 lb of fruit.
- 4 US dry quarts equal 1 US dry gallon (4.40488 L) and 8 dry quarts make 1 peck.
- Converting the other way, 1 liter equals about 0.9081 US dry quart.
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 a US dry quart?
One US dry quart equals about 0.466671 board feet, because a board foot is roughly 2.14 times the volume of a dry quart.
How do I convert US dry quarts to board feet?
Multiply the dry-quart figure by 0.466671. For example, 10 dry quarts equal about 4.667 board feet.
How many dry quarts equal one board foot?
About 2.142837 US dry quarts equal one board foot, the reciprocal of the factor.
Do board feet and dry quarts measure the same thing?
Both are volume units, though board feet describe lumber and dry quarts describe loose solids; the conversion is purely geometric.
Where is this conversion used?
It is a volume-magnitude comparison, occasionally handy when relating bulk material volumes to sawn-lumber quantities.
