Thousand Board Feet (MBF)

Definition: A bulk lumber unit equal to exactly 1,000 board feet, sized for wholesale and industrial timber quantities too large to conveniently express in individual board feet.

History: Adopted by the sawmill and timber industry as a natural bulk-scale extension of the board foot once shipments and mill outputs routinely reached thousands of board feet.

Current use: The standard unit for quoting sawmill production volumes, timber sale contracts, and wholesale lumber shipments in North America.

Cubic Inch (in³)

Definition: A small imperial volume unit — a cube measuring one inch on every side — useful for describing the volume of small pieces of wood or trim.

History: Derived directly from the imperial inch, used wherever finer volume resolution than the cubic foot is needed.

Current use: Occasionally used in woodworking for small-piece volume calculations, such as estimating material for trim, moulding, or small craft projects.

About These Parameters

Value
The amount of lumber or timber volume you want to convert, expressed in the "From" unit — a lumberyard's board-foot quantity, a firewood seller's cord count, or a sawmill's cubic-meter output.
From Unit
The unit your value is currently measured in — a hardware-store board-foot price, a firewood cord, a pulp mill's cunit, or a railroad's cross-tie count.
To Unit
The unit you want the result converted into. Use the swap button to flip From and To instantly, handy when translating between a retail unit like the board foot and a wholesale unit like the thousand board feet.

How Lumber Volume Conversion Works

The Formula

Every unit here is defined by a fixed multiplier relative to the cubic meter. To convert a value from one unit to another:

result = value × (factor of "From" unit ÷ factor of "To" unit)

For Thousand Board Feet → Cubic Inch: multiply by 143999.68. For example, 1 MBF × 143999.68 = 143999.68 in³.

The Board Foot and the Cord: America's Retail Lumber Units

The board foot became the North American lumber trade's standard as sawmills industrialized in the 19th century, giving buyers and sellers a consistent way to price sawn boards of varying width and length on the same volume basis. The cord predates it by centuries, going back to the colonial-era firewood trade — a stack 4 feet high, 4 feet wide, and 8 feet long (128 cubic feet including the air gaps between logs), literally measured out and bound with a cord of rope before sale, which is where the name comes from. Both units remain the everyday retail measures of the US and Canadian lumber and firewood trade today.

Wholesale and Industry-Specific Units

Once volumes move beyond individual retail purchases, the trade shifts to bulk and industry-specific units: the thousand board feet (MBF) scales the board foot up for sawmill production and wholesale shipment quotes, while the cunit (100 cubic feet of solid wood) gives the pulp and timber industry a shape-neutral wholesale unit for raw logs and wood chips that don't naturally divide into board-foot-shaped planks. Railroads use their own units entirely — the cross tie and the larger switch tie — to convert raw timber volume directly into the number of finished ties a given quantity will yield. Sheet-goods manufacturers, meanwhile, price plywood and OSB by the thousand square feet at a specific panel thickness, since surface area at a known thickness is how that segment of the industry has always measured volume.

Example

1 MBF equals 143999.68 in³. For scale, a single 2×4 stud 8 feet long is a little over 5 board feet, a full cord of firewood is 128 cubic feet stacked (about 80 cubic feet of solid wood once air gaps are excluded), and a standard cunit represents 100 cubic feet of solid timber — roughly the volume of several full-grown log sections.

Frequently Asked Questions

How many Cubic Inches are in 1 Thousand Board Feet?

1 Thousand Board Feet (MBF) equals exactly 143999.68 Cubic Inches (in³).

What is a board foot exactly?

A board foot is the volume of a plank 1 foot long, 1 foot wide, and 1 inch thick — 144 cubic inches. It's the standard unit US lumberyards use to price sawn boards and dimensional lumber, regardless of the actual length or width the board is cut to, since the volume (and therefore the board-foot count) is what determines the price.

Why is a cord 128 cubic feet but the "solid" cord only about 80?

A full stacked cord occupies 128 cubic feet (4 × 4 × 8 feet), but that figure includes the air gaps that naturally form between irregularly-shaped, rounded logs. Foresters estimate that only about 80 cubic feet of that stack is actually solid wood — the "cord (80 ft³)" unit on this page represents that estimated solid-wood content rather than the total space the stack occupies.

What's the difference between a cross tie and a switch tie?

Both are railroad timber-volume units representing one finished tie's worth of wood, but a switch tie is sized for the longer ties used at track switches and junctions, so it represents noticeably more volume than a standard cross tie used along straight track.

Why does the TSF (thousand square feet) unit change depending on panel thickness?

TSF measures a fixed surface area (1,000 square feet) of sheet material like plywood or OSB, but the actual volume of wood in that area obviously depends on how thick the panel is — a 3/4-inch panel contains six times as much wood as a 1/8-inch panel covering the same 1,000 square feet, which is why this page lists a separate TSF unit for each common panel thickness.
