how to calculate board feet

Calculating board feet is a common way to measure the volume of lumber. Here's how you can do it:

What is a Board Foot?

A board foot is a unit of volume for lumber, equivalent to a piece of wood that is:

• 12 inches long
• 12 inches wide
• 1 inch thick

Formula to Calculate Board Feet

To calculate board feet, use the formula: Board Feet = (Thickness in inches × Width in inches × Length in feet) ÷ 12

Step-by-step:

1. Measure the thickness of the board in inches.
2. Measure the width of the board in inches.
3. Measure the length of the board in feet.
4. Multiply thickness × width × length.
5. Divide the result by 12 to get board feet.

Example Calculation

Suppose you have a board that is:

• 2 inches thick
• 6 inches wide
• 10 feet long

Calculation:

• Multiply: 2 × 6 × 10 = 120
• Divide by 12: 120 ÷ 12 = 10 board feet

So, the board contains 10 board feet. If you have multiple boards, calculate the board feet for each and then add them together for the total volume. Let me know if you want help with specific measurements!
