Board foot to square foot converter

The board-foot is a specialized unit of volume for measuring lumber in the United States and Canada. Unfortunately, it is not truly a measure of volume, due to nominal and actual measures used in the lumber business. In addition, the definition is different for hardwood and softwood. Note that the cf of a 2x6x18' board is 1. However, for an area that is square feet with a depth of 1 inch, there are board feet present.

Using the lumber calculator: an example Let's assume you want to use this board foot calculator to determine how much you should pay for a few hardwood pieces. Decide on the number of pieces you want to purchase.

Let's assume it's five wooden boards. To calculate arc length without radius, you need the central angle and the sector area : Multiply the area by 2 and divide the result by the central angle in radians.

Find the square root of this division. Multiply this root by the central angle again to get the arc length. The units will be the square root of the sector area angle. Check your result with Omni Calculator. Or the central angle and the chord length : Divide the central angle in radians by 2 and perform the sin function on it. Divide the chord length by double the result of step 1. This gives you the radius. Typical recommendations for exterior walls are R to R, while R, R and R are common for ceilings and attic spaces.

Lumber Pricing Slab pricing will vary based upon wood species, character and size. However, all pricing is based on board foot. A board foot is a measure of wood volume. A typical 2,square-foot home uses almost 16, board feet of lumber and 6, square feet of structural panels like plywood.

Calculate the Studs Multiply the total wall length in feet by 0. Add three studs for each degree corner. Add four studs for each degree corner. Add two studs for each wall intersection where another wall abuts the wall you are estimating. Multiply the length times the width of the room to get the room square footage. So the total linear footage of the 1 x 12 boards is found by multiplying 5 boards by 6 feet which equals 30 linear feet.

Here are the steps for using this board feet calculator:. While both are measurements, the former is for volume, and the latter is for area. Most merchants use the board foot measurement, especially when you buy several pieces of lumber in different sizes.

You can convert this value to inches using the following formula:. When computing for board feet, pay attention to the units. This is because the length is usually expressed in feet, the thickness, and width, in inches.

Here are some steps to follow for board foot and cost computations. After computing, you can use the board foot calculator to check for correctness. When purchasing your lumber needs from a building supply store, you usually purchase these items per piece.

But buying in bulk from wholesalers and hardwood dealers will entail computations by board foot. They will compute your order by board feet.
