Calculating Volume: Board Feet and Cords

Understanding how to calculate the volume of logs is essential for budgeting and cost management in wood processing. There are two primary units of measurement: board feet and cords.

• Board Foot: A board foot is a unit of volume equal to 144 cubic inches. It’s typically used for measuring sawn lumber.
• Cord: A cord is a unit of volume equal to 128 cubic feet. It’s typically used for measuring firewood.

Calculating Board Feet:

The formula for calculating the board feet of a log is:

Board Feet = (Diameter in Inches - 4) * (Diameter in Inches - 4) * Length in Feet / 16

Example:

A log with a diameter of 12 inches and a length of 10 feet would have:

Board Feet = (12 - 4) * (12 - 4) * 10 / 16 = 40 board feet

Calculating Cords:

A cord is a stack of wood that measures 4 feet high, 4 feet wide, and 8 feet long. To calculate the number of cords in a pile of wood, you can use the following formula:

Cords = Length (ft) * Width (ft) * Height (ft) / 128

Example:

A pile of wood that measures 8 feet long, 4 feet wide, and 4 feet high would have:

Cords = 8 * 4 * 4 / 128 = 1 cord

Drying Time Estimation: Moisture Content and Seasoning

The moisture content of wood is a critical factor in determining its suitability for firewood. Freshly cut wood can have a moisture content of 50% or higher. For optimal burning, firewood should be seasoned to a moisture content of 20% or less.

Estimating Drying Time:

The drying time for firewood depends on several factors, including:

• Wood Species: Hardwoods generally take longer to dry than softwoods.
• Climate: Warm, dry climates are more conducive to drying than cool, humid climates.
• Stacking Method: Properly stacking the wood allows for better air circulation, which speeds up the drying process.
• Log Size: Smaller logs dry faster than larger logs.

As a general rule of thumb, firewood should be seasoned for at least six months to a year before burning.

Formula for Estimating Drying Time:

While there’s no precise formula for calculating drying time, you can use the following guideline:

Drying Time (Months) = K * (Initial Moisture Content - Target Moisture Content)

Where K is a constant that varies depending on the wood species and climate. For hardwoods in a temperate climate, K is typically around 0.2.

Example:

If you’re drying oak firewood with an initial moisture content of 50% and a target moisture content of 20%, the estimated drying time would be:

Drying Time = 0.2 * (50 - 20) = 6 months

The Global Perspective: Timber Prices and Fuelwood Markets
