Cross Tie (tie)
Definition: A railroad-industry volume unit representing the standard volume of a single wooden cross tie (the perpendicular beam supporting rail tracks).
History: Adopted by the railroad and timber industry to convert between raw log volume and the number of finished ties a given quantity of timber will yield.
Current use: Used by railroads and tie mills to estimate how many cross ties can be cut from a given volume of raw timber.
Switch Tie (tie (switch))
Definition: A railroad-industry volume unit representing the standard volume of a switch tie — a longer tie used at track switches and junctions, larger than a standard cross tie.
History: Adopted alongside the cross tie as a companion unit in the railroad timber trade, reflecting the larger dimensions switches require compared to standard track sections.
Current use: Used the same way as the cross tie, for estimating timber yield specifically for the larger ties needed at rail switches and junctions.

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 Cross Tie → Switch Tie: multiply by 0.63492063. For example, 1 tie × 0.63492063 = 0.63492063 tie (switch).
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 tie equals 0.63492063 tie (switch). 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 Switch Ties are in 1 Cross Tie?
1 Cross Tie (tie) equals exactly 0.63492063 Switch Ties (tie (switch)).
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.
