Calculating Wood Volume: Board Feet vs. Cords

Understanding how to calculate wood volume is essential for budgeting and cost management in wood processing. Two common units of measurement are board feet and cords.

Board Feet

A board foot is a unit of measurement for lumber. It represents a piece of wood that is 1 inch thick, 12 inches wide, and 12 inches long.

Formula:

Board Feet = (Thickness in inches x Width in inches x Length in inches) / 144

Example:

A board that is 2 inches thick, 8 inches wide, and 10 feet (120 inches) long contains:

(2 x 8 x 120) / 144 = 13.33 board feet

Cords

A cord is a unit of measurement for firewood. It represents a stack of wood that is 4 feet high, 4 feet wide, and 8 feet long, totaling 128 cubic feet.

Estimating Cords:

Estimating the number of cords in a pile of logs can be challenging, but here’s a general guideline:

1. Measure the Pile: Measure the height, width, and length of the pile in feet.
2. Calculate the Volume: Multiply the height, width, and length to get the total volume in cubic feet.
3. Divide by 128: Divide the total volume by 128 to estimate the number of cords.

Example:

A pile of logs that is 6 feet high, 8 feet wide, and 10 feet long has a volume of:

6 x 8 x 10 = 480 cubic feet

Estimated number of cords:

480 / 128 = 3.75 cords

Note: This is just an estimate, and the actual number of cords may vary depending on the size and shape of the logs and how tightly they are stacked.

Drying Time Estimation: The Science of Seasoning

Properly drying or “seasoning” firewood is crucial for efficient burning. The drying time depends on several factors, including wood species, log size, and climate conditions.

Factors Affecting Drying Time:

• Wood Species: Hardwoods like oak and maple take longer to dry than softwoods like pine and fir.
• Log Size: Smaller pieces of wood dry faster than larger pieces.
• Climate: Warm, dry climates promote faster drying than cool, humid climates.
• Stacking Method: Stacking wood in a single row with good air circulation will speed up the drying process.
• Sun Exposure: Exposing the wood to direct sunlight can also accelerate drying.

Estimating Drying Time:

As a general rule, hardwoods should be dried for at least 6-12 months before burning, while softwoods can be dried in 3-6 months.

Formula:

Drying Time (Months) = K x (Log Diameter in Inches)

Where K is a constant that varies depending on the wood species and climate.

• Hardwoods (Oak, Maple): K = 0.5 – 1.0
• Softwoods (Pine, Fir): K = 0.25 – 0.5

Example:

To estimate the drying time for oak logs with an average diameter of 10 inches in a temperate climate:

Drying Time (Months) = 0.75 x 10 = 7.5 months

Note: This is just an estimate, and the actual drying time may vary depending on the specific conditions.

Checking Moisture Content:

The best way to determine if firewood is dry enough to burn is to use a moisture meter. The ideal moisture content for firewood is below 20%.

Global and Regional Timber Prices and Fuelwood Market Rates

Understanding global and regional timber prices and fuelwood market rates is essential for making informed decisions about wood processing and firewood preparation.

Timber Prices:

Timber prices vary widely depending on the species, quality, and location. According to the Food and Agriculture Organization of the United Nations (FAO), global timber prices have been increasing in recent years due to increased demand and decreased supply.

• North America: Timber prices in North America are generally higher than in other regions due to high demand and strict environmental regulations.
• Europe: Timber prices in Europe are also relatively high due to sustainable forestry practices and limited supply.
• Asia: Timber prices in Asia are generally lower than in North America and Europe due to lower labor costs and less stringent environmental regulations.

Fuelwood Market Rates:

Fuelwood market rates also vary depending on the region and the type of wood. According to the U.S. Energy Information Administration (EIA), the average price of firewood in the United States is around $250-$400 per cord.

Regional Variations:

• Northeast: Firewood prices in the Northeast are generally higher than in other regions due to high demand and cold winters.
• Midwest: Firewood prices in the Midwest are moderate due to a balance between supply and demand.
• South: Firewood prices in the South are generally lower than in other regions due to mild winters and abundant supply.
• West: Firewood prices in the West vary depending on the location and the availability of wood.
