Calculating Wood Volume: Board Feet & Cords

Understanding how to calculate wood volume is crucial for budgeting and cost management in wood processing projects. The two most common units of measurement are board feet and cords.

Board Feet:

• A board foot is a unit of measurement equal to 144 cubic inches. It’s typically used for measuring lumber and timber.
• Formula for Calculating Board Feet: (Thickness in inches) x (Width in inches) x (Length in inches) / 144

Example:

• A board that is 2 inches thick, 12 inches wide, and 8 feet (96 inches) long contains: (2 x 12 x 96) / 144 = 16 board feet.

Cords:

• A cord is a unit of measurement equal to 128 cubic feet. It’s typically used for measuring firewood.
• A standard cord is a stack of wood that is 4 feet high, 4 feet wide, and 8 feet long.
• Estimating Cords from Log Diameter and Length: This is more complex and often involves using tables or online calculators. However, a rough estimate can be made by calculating the volume of the log in cubic feet and dividing by 128.

Example:

• A log with a diameter of 16 inches and a length of 10 feet has a volume of approximately 13.96 cubic feet.
• To estimate the number of cords in the log, divide the volume by 128: 13.96 / 128 = 0.11 cords (approximately).

Important Note: These are just estimates. The actual volume of wood in a cord can vary depending on how tightly the wood is stacked and the size and shape of the individual pieces.

Drying Time Estimation: Moisture Content & Wood Species

The drying time for wood is a critical factor in firewood preparation. Seasoned firewood burns more efficiently and produces less smoke than green firewood.

Factors Affecting Drying Time:

• Wood Species: Hardwoods like oak and maple take longer to dry than softwoods like pine and fir.
• Moisture Content: Green wood can have a moisture content of 50% or higher. Seasoned firewood should have a moisture content of 20% or lower.
• Climate: Warm, dry climates are ideal for drying firewood. Humid climates can significantly increase drying time.
• Stacking Method: Stacking firewood in a way that allows for good air circulation will speed up the drying process.

Estimating Drying Time:

• General Rule of Thumb: Hardwoods typically take 6-12 months to dry, while softwoods typically take 3-6 months to dry.
• Moisture Meter: Using a moisture meter is the most accurate way to determine the moisture content of firewood.
• Visual Inspection: Seasoned firewood will be lighter in weight and have cracks in the end grain.

Tips for Speeding Up Drying Time:

• Split the Wood: Splitting the wood into smaller pieces will increase the surface area exposed to air and speed up the drying process.
• Stack the Wood Properly: Stack the wood in a single row with good air circulation. Leave space between the rows.
• Elevate the Wood: Elevate the wood off the ground to prevent moisture from wicking up into the wood.
• Cover the Wood: Cover the wood with a tarp to protect it from rain and snow. However, be sure to leave the sides open to allow for air circulation.
